Potassium dichromate solution Essay 1. Deep colour of potassium permanganate solution will show out two meniscuses but according to burette using, we are try to measure the volume by different. Therefore if we technically use the same meniscuses in the all reading, it will be fine for the experiment. 2. Store the dilute hydrogen peroxide in a cool, dry and well-ventilated area. Also put it in a steel or glass and opaque container. On the other hand, keep away from heat, flame and light. Conclusion: In titration I, we standardize the iron(II) solution is 0. 10M with N-phenylanthranilic acid indicator and Barium diphenylamine sulphonate indicator.

Free College Essays - The Sun Motif in The Stranger by Albert Camus :: The Stranger The Outsider

The Sun Motif in The Stranger Many artists, authors, and composers have put the beauty and warmth of the sun in their work. The Dutch painter Vincent van Gogh created landscapes that expressed his joy with bright sunshine. The American poet Emily Dickinson wrote a poem called "The Sun," in which she described the rising and setting of the sun. The Russian composer Nicholas Rimsky-Korsakov included a beautiful song, "Hymn to the Sun," in his opera The Golden Cockerel. Uniquely, Camus' usage of the sun opposes its warmth and beauty in The Stranger. The sun is a symbol for feelings and emotions, which Monsieur Meursault cannot deal with. There is a sun motif present throughout the novel, which perniciously characterizes the usual fondness towards the sun. The sun is a distraction from Meursault's everyday life and he cannot handle it. The sun first presents a problem to Meursault at his mother's funeral procession. Even before the procession embarks, Meursault remarks of the sun, calling it "inhuman and oppressive." Meursault has shown no emotion towards his mother's death and he directs his bottled-up anxiety at the sun. To Meursault, the sun is an influence on all his senses, as he cannot hear what someone else says to him. He pours with sweat, symbolizing the flow of emotions. Meursault constantly thinks about the sun when one would expect him to be mourning his dead mother. He says, "I could feel the blood pounding in my temples," which is strong imagery. At the beach with Raymond, the sun provokes Meursault to commit a crime. He says, "(the sun) shattered into little pieces on the sand and water." While going to get a drink of water, the foreign Arab uses a knife to shine the sunlight in Meursault's face. Meursault knew that all he had to do was turn around and walk away. His emotions (again not shown externally and reserved) took over. Camus states, "All I could feel were the cymbals of sunlight crashing on my forehead and, instinctively, the dazzling spear flying up from the knife in front of me. The scorching blade slashed at my eyelashes and stabbed at my stinging eyes." This strong imagery forces Meursault to fire and kill the Arab with a revolver. What makes it worse, he fires four more times to make sure the sun is dissipated for good. In prison, Meursault changes his views on both the sun, and on his view of life, which are similar.

Compare Joy’s present job Essay

1. Compare Joy’s present job to what you think her previous job as a salesperson might have been. How are they similar? How are they different? Joy’s position as regional sales director is similar to her previous job as salesperson in that both are people-oriented. In the job as salesperson, she would have met with clients, traveled, and dealt with many people face-to-face. As a salesperson, however, she was in control of her own time. Her present job involves working through other people, and she must cope with many problems. The job is fragmented and involves communicating and negotiating. Thus, the managerial position is much broader in scope and contains many more day-to-day problems and interruptions. 2.What managerial skills are depicted in the case? Which skill is most important for Joy to possess? Why? Human and conceptual skills are most important in Joy’s present job–especially human skills. She works with subordinates, peers, and superiors–all requiring good human skills. 3. Why do you feel Joy may be disenchanted with her present job? The disenchantment may result from unrealistic expectations about the sales director’s job. Many people who have excellent technical skills and succeed at a technical job expect to continue performing the same tasks when they become managers. But as one moves up the management hierarchy, the various management functions become more important, and they require human and conceptual rather than technical skills. People who succeed as managers enjoy the opportunity to perform these functions and display these skills. For Joy, the greatest frustration seems to be her inability to control her own time and the need to work through other people, many of whom may disagree with what she is trying to accomplish. Thus, the key management issues become persistence and frequent negotiations.

Lack Of Alcohol Consumption On Campus - 2014 Words

Universities and colleges in the United States are split up into different categories. Private, public, four years, and two years are just some of the different types of colleges in the United States. To be even more specific all colleges are broken down into two major categories: dry and wet campuses. Dry campus are basically universities that do not allow alcohol consumption on campus even if you are at the drinking age. Wet campuses are the exact opposite. Most wet campuses are huge schools where they can not control the alcohol consumption, such as the University of Connecticut, Penn State, etc. Dry campuses on the other hand are mostly smaller schools where alcohol consumption can be monitored. Examples of this are ECSU, and all the other Connecticut state schools. The reasons for these differences are because the universities are trying to decrease the amount of drinking on campus, but does this actually work? is the percentage of alcohol consumption lower on dry campuses than wet campuses? After researching these topics and experiencing this first hand it is clear that the percentage of alcohol consumption on dry campuses is not low enough compared to the percentage in wet campus, to be considered a good way of solving the problem of binge drinking in universities. Dry campus restrictions don t work because they don t impede students from buying alcohol, they don t impede them from drinking off campus, and they fail to prevent alcohol related incidents.
