How to Conjugate the French Verb Détester

The French verb  dà ©tester  means to hate. Unlike some other verbs, this one is fairly easy to remember because of its similarity to the English word detest. As with the English verb, you would use  dà ©tester  to express an extreme dislike for something, such as food or a particular household chore youre not fond of. Like the majority of verbs in French,  dà ©tester is a regular verb. Conjugating Dà ©tester Verb conjugations can become a headache for French students because there are so many verb forms to remember. Not only does the infinitive ending change with each tense and mood, it also changes with each subject pronoun. For   example, I hate is je dà ©teste and we will hate is nous dà ©testerons. Its easier to memorize all these forms if you practice them in context and simple sentences. Subject Present Future Imperfect je dteste dtesterai dtestais tu dtestes dtesteras dtestais il dteste dtestera dtestait nous dtestons dtesterons dtestions vous dtestez dtesterez dtestiez ils dtestent dtesteront dtestaient Present and Past Participle The  present participle  of  dà ©testant  is formed by adding -ant  to the verb stem of  dà ©test. While its primarily used as a verb, you will find it useful as an adjective, gerund, or noun as well. Beyond the imperfect, another form of the past tense hated is the  passà © composà ©. This one is formed in a different manner and relies on the  past participle  dà ©testà ©. To complete it, you must also conjugate the  auxiliary verb  avoir.   As an example, I hated is jai dà ©testà © and we hated is nous avons dà ©testà ©. More Conjugations There will be times when you will need to imply some degree of uncertainty to the verb  dà ©tester  as well. For this, use the subjunctive verb mood. In a similar fashion, the conditional form is used when the hating is dependent on something else happening. You should not use the passà © simple unless youre reading or writing in French. The same applies to the imperfect subjunctive, though its a good idea to be able to recognize these as forms of  dà ©tester. Subject Subjunctive Conditional Pass Simple Imperfect Subjunctive je dteste dtesterais dtestai dtestasse tu dtestes dtesterais dtestas dtestasses il dteste dtesterait dtesta dtestt nous dtestions dtesterions dtestmes dtestassions vous dtestiez dtesteriez dtesttes dtestassiez ils dtestent dtesteraient dtestrent dtestassent The imperative verb form may be quite useful with  dà ©tester  because its often used in exclamations. When using it, the subject pronoun is not required: use dà ©teste rather than tu dà ©teste. Imperative (tu) dteste (nous) dtestons (vous) dtestez

The Body Is The Minds Gateway To The Outside World. The

The body is the minds gateway to the outside world. The passages The Phaedo and The Republic both talk about obtaining true knowledge and the issues that arrive from the body. In both of these, Plato talks through Socrates to explain philosophical viewpoints to the reader. In The Phaedo, the reader gets an account of the some of the final hours of Socrates life before his death. During this time, he discuss the relationship between the body and mind, and rationalizes that the body is merely a distraction from the truth. On the other hand, The Republic discuss how even though the body can provide distractions, philosophers can be able to reach towards the truth through harmony between the parts that make up a person. Thus, by examining†¦show more content†¦From nutrition to entertainment, the body is always in need of something. Likewise, the body can provide inaccurate depictions of reality. An example of this could be a mirage in the desert. The body may think it is seeing something, but in fact the sense are perceiving a false image. According to Socrates in the Phaedo, all these things can take away from a philosopher’s ability to reason and obtain the truth. Likewise, this same Idea also persists in the Republic. Plato argues that things like drama, poetry and painting provide imitations to the truth. These imitation can pose a threat by being allies for ‘inferior’ parts of the mind and leading mind away from truth (Sabina, 7). Although, to counter these arguments Morris states that even if the reality that is being sensed is inaccurate, it does not mean that it cannot be apprehended at all; it is still possible to understand reality, even if the reality being taken in is not entirely correct (Morris, 11). Some reality, even if incorrect, is better than nothing at all (Morris, 11). Granted, at the same time philosophers must be cautious not to fully believe everything being sense. This is why the Socratic Method is so important. Everything, even the truth, must be questioned to full understand the world. Even if a person knows that he/she want to control their body that may not always happen.

A Clean, Well

A Clean, Well-Lighted Place Essay Ernest Miller Hemingway was born in Oak Park, Illinois July 21, 1898. He died in 1961 at the age of 63. Hemingway is known to be one of the most influential writers of the twentieth century. He has written more than one hundred short fiction stories, many of them are well known around the world. Some of these short stories have had just as powerful an impact as his novels. As a young man, Hemingway left his hometown in Illinois to go to Europe, where he worked for the Red Cross during World War I. His time spent there inspired him to write some of his most famous novels, most of which spoke of the horrors of the war. For instance, A Clean, Well-Lighted Place by Ernest Hemingway is a short story that focuses on three different age groups and their varying views on life. By analyzing the three different points of view, we see Hemingways perspective of an old man. The story is about an old man that every so often, sits in a very clean bar, drinks away at two oclock in the morning and is the last one to leave. There are three waiters: one is a young man, one is an older gentleman, and the last is a very old man. All the waiters see him in a different way based on their ages. Furthermore, Ernest Hemingway had a different style of writing than the other authors of his time. The Sun Also Rises is the book that established Hemingway as a literary force and it introduced the world to the Lost Generation (5). The Lost Generation is referred to as the disillusioned that fought in the war. Two of the novels main characters, Lady Brett Ashley and Jake Barnes, typify the Lost Generation (1). This book has a lot of thematic issues, but the reader really needs to think to be able to pick up on all of them (2). Friendship, stoicism, and natural grace under pressure are offered as the values that matter in an otherwise amoral often-senseless world (1). His mind is set on writing only (3). The only thing Hemingway thought about was writing and finishing The Sun Also Rises. The writing is as strong and powerful as a swift kick to the head (4). This quote is referring to Hemingways strong and complex style of writing. Hemingway writes about the dreariness of everyday lif e but it is interesting at the emphasis on drinking during the age of prohibition (3). The only failing is that the messages he delivers are a little empty in that we know he delivers them in a way that we like (4). His morals are hard to understand unless you can achieve his state of mind. In conclusion, Hemingway shows us the different opinions people have based on their age and experiences, through the eyes of the three waiters. Most people assume things about others, especially of those they do not know, but we need to have an open mind and try to look through the eyes of a person, instead of just looking at them. Hemingway helps the reader see this and think twice instead of assuming. The Sun Also Rises was Hemingways best-selling novel and is still a popular book today. The Sun Also Rises was about the events that were taking place in Hemingways life. The Sun Also Rises can be related to real life by realizing that it was written from a mans real life experience.

NTUC FairPrice Co-operative Limited Essay Example

NTUC FairPrice Co-operative Limited Essay NTUC FairPrice Co-operative Limited is one of Singapore’s largest chains of supermarkets, department stores and convenience stores. It was founded in 1973 by the Singaporean labor union with the objective of influencing Singapore’s high cost of living through the implementation of regulated pricing on many everyday consumer goods. Currently, FairPrice’s vast 130-outlet supermarket chain includes concepts like FairPrice Finest, Fairprice Xtra and Fairprice Supermarkets. Meanwhile, Fairprice also maintains two convenience store lines namely: FairPrice Express and Cheers—with both having a combined network of more than 150 branches. In response to the growing demand for online shopping, the company has also launched FreshPrice Online—a web platform that enables shoppers to buy their groceries online and have them delivered straight to their homes. FairPrice’s multiple and diverse selling channels enable them to serve more than half a million customers on a daily basis (FairPrice, 2017). According to Bloomberg (2017), FairPrice’s outlets offer mainly products like food items, beverages, frozen goods, fresh produce, alcohol, toiletries, health and beauty items and other similar merchandise. Aside from its regular retail and grocery operation, the company also maintains warehousing, trading and distribution businesses.

Singapore, being a largely commercial and highly urbanized country, is mostly unable to grow its own agricultural products that are needed in the production of food and beverage goods. This being the case, the country is largely dependent on international trade with countries like the United States, Australia, a large part of Europe and the Middle East. The country maintains a relatively open economy—being able to conduct business with the aforementioned countries with minimal sanctions and restrictions. In fact, the Singaporean government does not impose any import taxes on most food and beverage products with the exception of tobacco and alcoholic goods. The government’s openness on international trade may implicate a great advantage for FairPrice whose merchandise are primarily imported food and beverage goods (USDA Foreign Agricultural Service, 2015). Economic Factors Economic factors pertain to key trends concerning consumer’s disposable income, general unemployment levels, interest rates, inflation rates and other economic indicators that can affect a populace’s willingness and ability to buy and to consume goods (Aguilar, 1967). According to Tang (2017), despite the general slowdown of the Singaporean economy in the recent years, the country achieved higher than expected economic growth in the final quarters of 2016. In fact, Singapore’s economy expanded by 1. 8 percent from 2015 to 2016. The country’s gross domestic product also grew by at least 9. % during the final quarter of the year. While this proves to be a positive sign for the economy, he still warns that 2017 may be marred with dismal business growth and a lack of consumer confidence as the Singaporean economy may get affected by the continued weakening of the Euro, the slowdown of the Chinese economy and the protectorate stance of the Trump administration. These events along with the fact that Singapore continues to be one of Asia’s most expensive cities to live in can cause great concern for customers and may seriously affect their ability to spend on consumer goods. Social Factors Social factors primarily pertain to the general behavior and mindset of a group of consumers. Particularly, it can pertain to their current set of preferences as dictated by their demographic profile, psychographic dispositions and the presence of new trends in the market (Aguilar, 1967). Singapore’s populace is generally characterized by a highly productive and fast-paced workforce. In fact, Singaporeans are known to clock in an average of 46 working hours per week—one of the highest in the world (Ministry of Manpower, 2015). This may have led many customers to develop of culture of convenience—opting for activities and services that can help them save time and be more productive. Firstly, this could mean a sustained increase for demand of instant and easily prepared food items. Secondly, it could also mean that more and more users are open to trying and subscribing to their online platform. Technological Factors Technological factors pertain to the advancements that can significantly improve a business’ internal and external operations. They may pertain to new discoveries that can help create new products or services or to new innovations that can streamline systems and costs (Aguilar, 1967). Being a highly urbanized society, the Singaporean market has become highly dependent on technology. This includes grocery shopping. In a study conducted by Shandwick (2014) about general grocery shopping behavior, more than 60% of the respondents claimed to prefer buying instant and readily prepared meals and goods. In the same year, more than 200,000 shoppers bought their groceries online to be able to save time and effort in shopping for their everyday needs (Jenner, 2016). This could imply a huge opportunity to grow FreshPrice Online. Environmental Factors Environmental factors pertain to the general attitude of customers and the stance of the government when it comes to preservation of the natural environment. The company may be affected by laws on waste management, energy consumption regulations, general environment protection sanctions and even the public’s perception on a company’s responsiveness to environmental issues. According to National Environment Agency (2017), Singapore’s daily solid waste output has reached 8,400 tons a day—marking an eight-fold increase from its waste output from the 1970s. This continuously increasing trend has forced the Singaporean government to implement a more systematic public waste collection scheme and a more stringent illegal dumping law. Being one of the largest producers of solid food waste in the country, FairPrice took a proactive stance and led the implementation of the Food Waste Index that essential measures and tracks the waste the company produces on a periodic basis. It is the first step towards the implementation of other key initiatives (Zero Waste Singapore, 2015). Legal Factors Legal factors pertain to the stringency of the government and other governing bodies in key aspects of business operations. These factors may cover employment regulations, workplace safety requirements, product testing procedures, anti-trust laws, competitive regulations and other similar factors. According to Shaffer (2013), Singapore’s fairly controversial position of limiting the influx of foreign laborers in the country had significant detrimental effects on many food and retail establishments. Since as much as 40% of Singapore’s population can be considered foreigners, the government’s stance has cut businesses’ access to affordable labor—hampering their ability to expand swiftly. Porter’s Five Forces Analysis Threat of New Entrants (Low) The threat of new entrants in any industry implicates the possibility of losing market share to new players, hence having to split returns and profits amongst many competitors (Porter, 1985). In the case of FairPrice, the threat of new entrants can be considered low. Firstly, entering the supermarket and grocery industry requires substantially large capital to be devoted to the purchase of expensive real estate, building and infrastructure requirements as well as the different facilities and fixtures used in day to day operations. The business will also require huge investments in inventories, warehousing and wages for the labor force. Bargaining Power of Buyers (Moderate) The bargaining power of buyers implies the customer’s influence and capability to put pressure on the company to make changes in their strategies (Porter, 1985). In the case of FairPrice, this can be considered only moderately threatening. For instance, individual customers purchase in relatively small quantities which create a fairly insignificant portion of the company’s total sales. The decisions of one customer may prove immaterial in the long run. However, in the unlikely scenario where FairPrice decides to increase prices or suffers from the poor service of their personnel, it is not impossible for customers to opt for different supermarkets. Bargaining Power of Suppliers (Low) Likewise, the bargaining power of suppliers pertains to their ability to put pressure and influence the strategic decisions of a company. Because of the scale of FairPrice’s operations, the bargaining power of suppliers can be considered significantly low. Suppliers may prove to be very careful in negotiating and doing business with a client of over a hundred branches as they may be easily replaced with a different brand. In fact, FairPrice may have enough leverage to demand the lowest prices and the biggest margins from its many suppliers. Threat of Substitutes (Moderate) The threat of substitutes pertains to the propensity of current customers to try out alternative products and services (Porter, 1985). In the case of FairPrice, this can be considered as a moderate threat. On one hand, online shopping has yet to capture a significant portion of the market to be considered highly threatening. However, the threat for substitutes can be considered relatively high in some product lines that FairPrice is carrying such as alcoholic beverages, hair care products, cosmetics and others similar goods. Customers may easily opt to purchase them in other shops such as liquor shops, drugstores and the like. Competitive Rivalry (High) FairPrice has equally popular and trusted competitors in the likes of Dairy Farm Singapore, Sheng Siong and Cold Storage (Singapore Business Review, 2012). Because the prices for consumer goods are relatively transparent and easily comparable, small variations in pricing can cause customers to prefer a competitor over another. Besides the proximity of the grocery stores from their residences or offices, there is very little motivation to keep customers loyal to a single line of grocery. Management Recommendations Prioritization of FairPrice Online While it can be said that there is still minimal demand for online grocery shopping, the steadily increasing adoption rates and customer usage suggest that the channel can be a significant contributor to sales in the next few years. If FairPrice could occupy and dominate the online grocery shopping market first, it may help avert tight competition in the future. It may be an opportune time for FairPrice to invest heavily in marketing their platform through the use of social media, in-store advertising through their shops and subsidized promotions amongst many other options to try and raise the adoption level amongst Singaporeans. Creating and Improving Customer Loyalty Programs The Five Forces Analysis reveals that while FairPrice can be considered one of the stronger players in the grocery market, it is still susceptible from losing customers due to tight competition. One way to address such an issue is improve the already-existing NTUC Plus Card which entitled frequent buyers to rebates. Instead of just offering rebates, allowing loyal customers to choose from a wider range of rewards like free travel, discounted spa treatments, and other lifestyle-based rewards could prove compelling. In addition, FairPrice could tie up with leading electronics, luxury or fashion brands and have them offer exclusive deals to the most loyal customers. Maximizing Environmental Programs FairPrice’s proactive stance on environmental programs could be a source of sustainable competitive advantage. FairPrice may invest in a full-blown department solely devoted in studying its environmental and waste footprint and finding ways to reduce them through technology. Firstly, such an investment can pay off in savings from avoiding waste products. Secondly, FairPrice can strengthen the reputation of its brand. Reinforcement of Concepts’ Branding While the FairPrice brand remains popular and distinct, the concepts under it like FairPrice Xtra and FairPrice Fresh amongst others may benefit from further brand building. By differentiating and specializing each one, they could occupy different spaces in the market and further reinforce the market leadership of FairPrice. A good start could be the launch and maintenance of separate marketing communications campaigns for each one. Conclusion The PESTEL Analysis reveals a relatively favorable external environment for the continuous growth of Fair Price. Despite the underperformance of the economy, the Singaporean government remains very supportive of major business activities like importation and exportation. Technological advancement has made it easier to cope with an ever-changing changing customer profile and preference. And by taking a proactive stance, FairPrice is able to manage most environmental and legal issues surrounding their business. On the other hand, the Five Forces Analysis reveals the innate strength of the FairPrice brand and organization. With the large scale and span of its operations, FairPrice is susceptible to few risk factors aside from the perennially tight competition amongst players.

Experiments with Metals and Ions of Metals free essay sample

Metals react with non-metals but each to a different extent. The most reactive metals are alkali metals (group1A, where group is a vertical column in the periodic table), which include lithium, sodium, potassium, rubidium, cesium and francium. All these metals have one electron in the valence electrons shell; this electron can be removed relatively easily, which means that this electron has a very small ionization energy. If we look closely at the elements of this group, we can see that they are not reactive to the same extent. This is because electrons have a negative charge and they are attracted o the nucleus, which has a positive charge. Valence shell electrons are responsible for the reactivity of an element; as the distance between valence electrons and the nucleus increases, the attractive force decreases and so the energy needed to separate the valence electron from an atom (ionization energy) decreases. So we can say that as the size of a metal atom increases, its ionization energy decreases and its reactivity increases (the most reactive alkali metal is francium and the least reactive one is lithium). We will write a custom essay sample on Experiments with Metals and Ions of Metals or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page An example of the reactivity of alkali metal is their reaction with water. For example: Na (s) + 2H20 †+ 2Na+(aq) + 20H -(aq) + H2 (g) + heat We can identify this reaction by the following 2- 3- 4- H2 gas emerges Disappearance of metals Heat produced The appearance of hydroxide ions (OH-(aq)) makes the solution basic, which can be identified by using phenolphthalein as the indicator. We can compare between the metals by the rate of production of H2(g) as well as by the heat produced from this reaction. Alkaline earth elements (group IA) are active metals but less than alkali metals. Since calcium is larger than the magnesium atom, its ionization energy is smaller than that of magnesium. Thus, calcium is more reactive than magnesium. The other metals as aluminum, zinc, iron, lead and copper do not react with water, so we cant use water to distinguish between their reactivity. HCl(aq) is used to put them in order according to their reactivity. We can put the most common metal in a series according to their reactivity (from the most to the least reactive one). Potassium, sodium, lithium, calcium, magnesium, aluminum, zinc, iron, lead, copper, silver . When a metal in the upper part of the reactivity series reacts with aqueous solution of other metal ions lower in the series, the more reactive metal eactive metal transfers its electrons to the less reactive metal. According to this reactivity series, we can predict what will happen when a piece of zinc metal is put in CuS04 (aq) soluti on or in MgS04 (aq) solution. Since Zn is more reactive than Cu, when we put Zn in CuS04(aq), a reaction will occur as follows: Zn (s) + Cu2+(aq) + S042- (aq) †+ Zn2+(aq) + S042- (aq) + Cu (s) However, Since Zn is less reactive than Mg, if we put Zn in MgS04(aq) there will be no reaction at all: Zn (s) + Mg2+(aq) + S042- (aq) †+ No reaction.

Reactions of chlorine, bromine and iodine with aluminium In this demonstration experiment, aluminium reacts with each of three halogens, chlorine, bromine and iodine. Spectacular exothermic redox reactions occur, ccompanied by flames and coloured smoke, forming the solid aluminium halides: 2Al + 3X2 -+ 2AlX3 (X = Cl, and l) Read our standard health safety guidance Lesson organisation This is a class demonstration that shows the spectacular reactivity of three non- metals from Group 7 with a metal. These experiments must be done in a fume cupboard as both the reactants and products are hazardous. Teachers attempting this demonstration for the first time are strongly advised to do a trial run before doing it in front of a class. Each experiment should take about 5 minutes. Apparatus and chemicals Eye protection Thick chemically-resistant gloves such as marigold industrial blue nitrile Access to a fume cupboard The teacher will require: Mortar and pestle Heat resistant mat, 30 x 30 cm Watch glasses, about 10 cm diameter, 2 Reduction tube (see note 1) Test-tubes, 3 Test-tube rack Teat pipette Filter paper Spatula or wooden splint Bosses, clamps and stands Chemicals for one demonstration: Aluminium foil, a few cm2 Aluminium powder (Highly flammable, Contact with water may liberate hydrogen), 0. 3 g Liquid bromine (Corrosive, Very toxic), 1 cm3 (see note 2) Solid iodine (Harmful), 2 g Silver nitrate solution, about 0. 1 mol dm3 (Low hazard but stains skin and clothing at this concentration), about 10 cm3 A little deionised water in a washbottle chlorate(l) solution (14% (w/v) available chlorine) (Corrosive), about 100cm3 Hydrochloric acid, 5 mol dm-3 (Corrosive), about 50 cm3 Technical notes Aluminium powder (Highly flammable, Contact with water may liberate hydrogen) Refer to CLEAPSS Hazcard 1 Liquid bromine (Corrosive, Very toxic) Refer to CLEAPSS Hazcard 15A, SRA04 The aluminium/bromine reaction Solid iodine (Harmful) Refer to CLEAPSS Hazcard 54A Silver nitrate solution (Low hazard at concentration used) Refer to CLEAPSS Hazcard 87 and Recipe card 58 Chlorine (Toxic, Irritant) Refer to CLEAPSS Hazcard 22A and Recipe card 26 Sodium chlorate(l) solution (Corrosive) Refer to CLEAPSS Hazcard 89 Hydrochloric acid (Corrosive) Refer to CLEAPSS Hazcard 47A and Recipe card 31 1 The reduction tube should be fitted with a one-holed rubber stopper fitted with short length of glass tubing and attached to the chlorine generator. Alternatively an 8-10 cm length of wide bore glass tubing with a stopper fitted with a short length of glass ubing at each end could be used see diagram. Wear suitable protective gloves (thick, chemically resistant) when handling liquid bromine. Have 500 cm3 of 1 mol dm-3 solution of sodium thiosulfate available to treat any spillages on the skin. Procedure HEALTH SAFETY: Wear eye protection and gloves Reaction of A1 + C12 a Set up the chlorine generator in a fume cupboard. Make sure it is securely clamped. b Loo sely crumple a piece of aluminium foil (10 x 5 cm) so that it will Just fit inside the reduction tube and push it into the tube. Attach the tube to the generator ith a short length of rubber tubing and clamp it in position at the end nearest to the generator, so that the aluminium foil can easily be heated using a Bunsen burner see diagram. c Generate a gentle stream of chlorine by dripping the hydrochloric acid slowly on to the sodium chlorate(l) solution, and allow it to pass over the aluminium. When the green colour of the chlorine gas fills the reduction tube, start heating the aluminium foil with a Bunsen burner at the end nearest to the chlorine supply. Once the aluminium is hot, a bright glow will suddenly appear where it starts to react with chlorine. Remove the heat. The bright glow should spread along the aluminium. If not, heat again, and increase the flow of chlorine gas. A lot of white smoke aluminium chloride is produced, some of it condensing as a white powder on the walls of the reduction tube and the rest streaming out of the hole in the end of the tube. When the reaction is over, stop the chlorine supply and remove the heat. e When the reduction tube has cooled down, disconnect it and, still in the fume cupboard, scrape a little of the white powder into a test-tube. Add a little deionised/ distilled water to the solid to dissolve it. Care: the reaction between anhydrous aluminium chloride and water can be quite vigorous an audible hiss can often be heard see Teaching Notes. f Test a drop of the solution with Universal indicator paper. It is strongly acidic. Test the remainder with a little silver nitrate solution. A white precipitate forms, showing the presence of chloride ions. Reaction of A1 + Br2 a Tear or cut some aluminium foil into several small pieces about 2 x 2 mm in size. fume cupboard. Sprinkle a few pieces of aluminium foil on to the surface of the bromine. Within a minute there are flashes of flame and a white smoke of aluminium romide is formed, together the orange vapour of bromine. Carefully hold another watchglass over the reaction to condense some of the smoke on to its surface as a solid. b Wash any aluminium bromide collected in this way off the watchglass into a test-tube using a little deionised water (Care: see Teaching Notes below). Test the solution with indicator paper and silver nitrate solution as above. The solution is acidic and a cream precipitate of silver bromide is formed. Reaction of A1 + 12 a Weigh out 2 gof iodine, which should be dry, and grind it to a powder in a fume cupboard, using a mortar and pestle. Place the powdered iodine on a filter paper on a dry heat resistant mat and add 0. 3 g of aluminium powder to it. Mix the two solids together in the fume cupboard using a wooden splint do not grind them together. When they are thoroughly mixed, pour the mixture into a heap on the heat resistant mat or in a metal tray, such as a tin lid, positioned in the middle of the fume cupboard. b To start the reaction, use a teat pipette to place a few drops of water on the mixture. After a time lag, the water begins to steam and clouds of purple iodine vapour are given off, indicating that an exothermic reaction has started. After a few more seconds sparks are given off and the mixture bursts into flame. When the reaction subsides, a white residue of aluminium iodide remains. Scrape a little of this into a test-tube (Care: see Teaching Notes below), add some deionised water and filter if necessary. Test the solution with indicator paper and silver nitrate solution as above. The solution is acidic and a yellow precipitate indicates the presence of iodide ions. Teaching notes These reactions make quite spectacular demonstrations in themselves, the bromine + aluminium reaction even more so in a partly darkened room. Classroom management n semi-darkness (Practical Physics advice) The demonstrations can be used to show the reaction between reactive non-metallic elements and a fairly reactive metal to form compounds, or as part of the study of the reactions of the Group 7 elements. Here the apparent order of reactivity is not that predicted from their position in the Group (that is chlorine †+ bromine †+ iodine). This is because of the different physical states of the three halogens, and the different surface area of the aluminium as a powder or foil. This can be used to make an important point about fair comparisons of reactivity. These reactions also serve to show that aluminium is in fact a more reactive metal than it appears in everyday use. The protective oxide layer of aluminium has to be penetrated by the halogens before the reactions can start, hence the delays, and the need for water to assist the two solid elements getting into contact, in the case of aluminium and iodine. The clouds of iodine vapour released when aluminium and iodine react can stain the inside of a fume cupboard. Teachers may prefer to demonstrate this reaction outdoors, if possible. The anhydrous aluminium halides are vigorously hydrolysed (sometimes violently if freshly prepared nd hot, as here) by water, giving off fumes of a hydrogen halide and a forming an acidic solution of the aluminium salt. To dispose of the solid residues, allow them to cool completely before adding in small amounts to 1 mol dm-3 sodium carbonate solution in a fume cupboard. Wait until the reaction has subsided before adding Allotropes of sulfur Sulfur is heated slowly and steadily from room temperature, so that all the changes in colour and consistency as it melts and eventually reaches boiling point, can be observed. A fresh sample of sulfur is heated to Just above the melting point, then llowed to cool and crystallise slowly as monoclinic sulfur. A further sample is heated to boiling point, and the liquid rapidly chilled in cold water to form plastic sulfur. A separate sample of sulfur is dissolved in a warm solvent, and the solution allowed to cool and evaporate, leaving crystals of rhombic sulfur. All the observed changes in properties can be related to the different molecular structures of the three solid forms of sulfur, and to the changes in structure as the temperature of liquid sulfur is gradually raised. Read our standard health safety guidance This practical is described here as a demonstration. However, some teachers may wish to consider whether certain parts could be used as class practicals with appropriately skilful and reliable classes. A demonstration, without any accompanying discussion about the possible reasons for the changes in properties in terms of structure, would take up to 45 minutes. However, to derive maximum benefit from the experiment, more time needs to be allowed for such discussion. Apparatus and chemicals Heat resistant gloves Access to a fume cupboard Flexicam or similar camera, digital microscope, digital projector and screen or other ethod of projecting images of small crystals to the class (as available). Boiling tubes, 4 (see note 4) Test-tube holders, 2 Stands and clamps, 2 Conical flask, 250 cm3 Cork, to fit conical flask Beaker (250 cm3), 2 Beaker, 1 dm3 (see note 5) Thermometer, O 250 oc Petri dishes or watchglasses, 4 (or more) Bunsen burner, tripod and gauze Electric hotplates, 2 (optional, if available) Heat resistant mats, 2 Filter paper, about 18 20 cm diameter Spatula Paper clips Damp cloth (to extinguish small sulfur fires) Dimethylbenzene (xylene), (Harmful), 100 cm3 (see note 2) Cooking oil (Low Hazard), 700 cm3 (see note 3) Dimethylbenzene (xylene) (Harmful) Refer to CLEAPSS Hazcard 46 Sulfur (Low hazard) Refer to CLEAPSS Hazcard 96A Cooking oil (Low hazard) 1 The sulfur used must be roll sulfur, crushed toa powder. To crush the rolls of sulfur, place in a strong plastic bag on a hard surface. Use a hammer or a vice to break up the roll sulfur into small pieces, then crush to a powder in a mortar and pestle. Flowers of sulfur is not suitable because it contains a lot of insoluble amorphous sulfur. During the experiments sulfur may catch fire, releasing sulfur dioxide (Toxic refer to CLEAPSS Hazcard 97), which may cause breathing difficulties o some students. If this happens, extinguish quickly by placing a damp cloth over the mouth of the test-tube. If the combustion cannot be extinguished quickly, the test-tube should be placed in fume cupboard, and the fan left running. 2 Although other hydrocarbon solvents, such as methylbenzene, can be used to dissolve sulfur and form monoclinic sulfur, dimethylbenzene (xylene) is the least hazardous. 3 If suitable cooking oil is not available, other clear, high-boiling oils may be used, e. g. paraffin oil (Refer to CLEAPSS Hazcard 45B). 4 These are large (1 50 x 25 mm) test- ubes, and should be clean and dry. The test-tubes in which sulfur has been heated can be difficult to clean for general use. It may be worth keeping a set of such tubes from year-to-year for this experiment. 5 The large beaker containing the cooking oil functions as an oil-bath for heating the sulfur slowly and uniformly, while allowing students to see clearly what is happening to the sulfur. Other containers may be preferred for the oil-bath, provided the visibility is maintained, for example by use of a webcam and digital projector. Procedure HEALTH SAFETY: Wear eye protection. Before the demonstration: a Pre-heat the oil-bath to about 130 oc, and maintain this temperature. b Clamp one of the sulfur-containing tubes in the oil bath, so that the sulfur is below the level of the oil in the bath. c Half fill the 250 cm3 beaker with cold water. d In the fume cupboard, put about 10 g of powdered roll sulfur into the conical flask and add about 100 cm3 of dimethylbenzene. e Prepare filter paper cone held together by a paper clip and supported in a beaker, as shown below: The demonstration: a Two-thirds fill two test-tubes with powdered roll sulfur (about 20 g in each tube) nd place in the oil bath. The sulfur will melt to a transparent, amber, mobile liquid in about 15 minutes. b Remove one tube from the oil-bath and pour the molten sulfur into the filter paper cone. Allow the sulfur to cool slowly and solidify, forming a crust. c Break the crust with a spatula and, handling the filter paper cone with heat resistant gloves, tilt it so that any remaining liquid flows out of the cone of solidifying sulfur on to a piece of scrap paper or card (for disposal). Needle-shaped crystals of monoclinic sulfur will be seen inside the hollow cone.

Career Change Consider These 5 Ways to Reinvent Yourself

Career Change Consider These 5 Ways to Reinvent Yourself Looking for a new job? Don’t pigeon-hole yourself by only considering opportunities similar to your established career path or what your degree says you are qualified to do. If you are going in a totally new direction with your career, it may require reinventing yourself, utilizing hidden skills and talents, and setting a goal to enjoy your new job more than you ever thought possible. As the poet Robert Frost wrote, â€Å"Two roads diverged in a wood, and I took the one less traveled by, and that has made all the difference.† So your new path may not be the most obvious one to take, but forging in a new direction can be very rewarding.How to Reinvent Your CareerIf you are looking for a change in employment; a job that will be rewarding and actually make you excited about heading to work each day, that job you seek may not even be on your radar.Reinventing your career requires thinking outside of the box (another job skill, by the way). Focus more on your hidden talents and the skills you have acquired through your work experience, in your personal life, or through volunteer work. Look down a different path, rather than the obvious direction of your work history or what you majored in college.What Skills Does a New Employer Seek?You have hidden skills and talents. Whether you mastered creating extraordinary PowerPoint presentations or your were in charge of entertaining your company’s clients while they were in town, you acquired extra skills along the way.So how do you identify these hidden talents and use them to find a new job or career? Here are the basic steps to reinventing yourself and finding a new career path.First, think about any skills you learned at other jobs, especially the ones that were never part of your job description, yet were required for you in order to succeed. This is a tough one because it requires really thinking about what was expected of you in moments where probably not a lot of recognition was given. These were side-skills and until now, nobody paid attention to them.Now begin writing a skill list and include all of your soft-skills as well as hard skills. While it is great that you are a PowerPoint guru, employers want to know that you have the insight to know what should go into a presentation that will reach the audience, motivate a client, or entice a customer. Write down instances where critical thinking and being keenly aware of underlying messages were something you tapped into.Add to your list any examples of being a persuasive public speaker. According to Prinstonreview.com, strong public speaking or presentation skills are vital for many career paths you might take. Think of it as the ability to sell or influence others, which could apply to a myriad of career options.Think about the research skills you have developed through your experience. Whether a career in law, marketing, teaching, politics or public relations, having a solid understanding of research methods will be a val uable asset for employers.If you are skilled at writing and communication then you are in luck. One of the top skills employers look for is good communications skills. If you can write or edit copy, there are many opportunities in which to use these skills. Above all, employers are looking to hire candidates with outstanding communication skills and who are team players, according to results of National Association of Colleges and Employers (NACE) Job Outlook 2013 survey.Finally, consider out of the ordinary experiences you have had on the job. This is a vast topic because there are so many ways you may have developed creative skills or sharpened organization capabilities. Have you excelled in illustration and design activities at work? Perhaps you were placed in charge of planning and orchestrating your company’s elaborate 10th-anniversary dinner party or an awards banquet?Creative or organizational skills like design or event management are needed in so many different forms of employment. Never leave those little extra talents you possess, like creativity or your ability to manage multiple tasks, off of your list.Think that focusing on your experience and expanded skill-set will not net you a solid job offer? Think again. According to a survey conducted by NACE, a vast majority of employers look more to hands-on experience and those extra skills, the ones most people don’t think twice about, when they are considering applicants.Now you are ready to consider new job opportunities, utilizing additional skill-sets and talents that you previously might have overlooked when searching for a new job. If it is time to explore new career possibilities, sign up with TheJobNetwork, include any hidden-skills that you possess on your resume, and head down a new path to your future.

Smoking Cessation Research Paper Example | Topics and Well Written Essays - 750 words

Smoking Cessation - Research Paper Example Quitting the practice of smoking has been tried by many and many have even successfully accomplished it. There are several who wish to quit smoking but their attempts have failed. CDC reports that 68% of the smokers who fall into the adult population have tried to either give up on this practice and are willing to live their lives without smoking (cdc.gov, 2014). The benefits of smoking cessation can be categorized into long term as well as short term benefits. Smoking cessation has psychological, social as well as physical benefits for smokers as well as people and the environment around the smokers. Smokers are a population that is frowned upon in social settings and people tend to disassociate themselves from smokers because smokers tend to smell bad and smoking even leads to the degradation of the smoker’s teeth and this negatively impacts their public profile. Due to these smokers face difficulty in making friends especially in groups comprising of nonsmokers. Quitting sm oke can help the smokers in eliminating bad breath and help in developing a positive social image and this can in turn increase their social acceptability. Smoking is heavily held responsible as a cause of death and this is because smoking has been found to lead to severe illnesses which ultimately take the lives of smokers. CDC reports that smoking of tobacco leads to severe illnesses which leads to deaths that are premature in nature and by quitting tobacco smoking, individuals can reduce the risk of premature death (cdc.gov, 2014). Smoking has even been recognized as one of the factors that negatively impacts the psychological health of individuals. According to Parrott, smoking is considered as a reliever of stress but it is one of the reasons that further increase the levels of stress. This means that by quitting tobacco smoking, quitters can relieve their psychological issue of stress. There are
