4/27/11 SYNTHESIS AND CHEMILUMINESCENCE OF LUMINOL Abstract: Chemiluminescence occurs in nature and can be found in everyday products. For example‚ the light omitted by fireflies‚ deep sea fish and glow sticks is a result of this process. Luminol was synthesized from from 3-nitrophthalic acid and then combined with potassium ferricyanide and hydrogen peroxide to omit a blue light. The product of this reaction is very unstable and is made by losing a nitrogen and the electrons go from an excited

Synthesis Paper for Langston Hughes Introduction: Love is often regarded as an emotion that invokes extreme joy‚ hope and excitement. For example‚ Romeo and Juliet were a young couple who were so excited and hopeful about their love that they were willing to do anything to be together. However‚ there is another side to the feeling we call love that isn’t so joyous.

Nikki Vietz Ms Bontekoe Honors English 11 3 October 2013 Synthesis Essay By changing the word “nigger” to “slave” defeats the purpose of the Adventures of Huckleberry Finn being a historical piece of literature. Such a change means ignoring the past and the word “nigger” is part of that past. “Nigger” is demeaning and insulting but is its replacement any less demeaning and insulting. Changing the word would not only destroy the message that Mark Twain was trying to convey‚ but also America’s history

EXP-10 CHEM 233L SYNTHESIS OF p-BROMOANILINE Introduction: In this experiment‚ p-bromoaniline was synthesized in three steps starting from aniline. Since the amino group of aniline is a strong activator of aromatic ring‚ direct bromination is impractical (equation 1). In order to make a desired product‚ amino group needed to be protected as the acetamide which also maintained ortho and para position but slowed down the rate of reaction (equation 2). Slow reaction rate would increase

The objective of this experiment was the synthesis of Isopentyl Acetate using an esterification reaction between acetic acid and Isopentyl Alcohol‚ using a strong acid as a catalyst. The product was washed‚ and distilled. This approach is called Fisher esterification‚ whereby esters are produced by the esterification of a Carboxylic acid where it is heated with an alcohol in the presence of a strong acid which acts as a catalyst. The ester produced had a banana flavor. The extraction of the

Synthesis With all the foreigners crossing the borders of the United States‚ America is considered to be a nation of immigrants. The United States has all kinds of immigrants who decide to relocate to America in order to pursue better opportunities for themselves than what they could find in their own country. Once the immigrants make it passed American borders‚ they begin living the "American way"‚ and doing what they think will help lead to a positive movement within the community. What the

Synthesis Essay Reactions to death and tragedy range depending on the cause and effect of the situation. People react differently to every situation‚ but with tragedy and death‚ a common reactions can range from anger to depression to fear. All of these can be authentic responses‚ but the question is whether these reactions are appropriate. In circumstances of tragedy and death‚ emotional responses are appropriate when they are authentic and additionally evoke action. In times of death and tragedy

Synthesis of Methyl Stearate The purpose of this lab was the convert liquid methyl oleate to solid methyl stearate by catalytic hydrogenation. Firstly‚ we produced hydrogen gas using solid mossy zinc and sulfuric acid. Using the hydrogen produced in the previous reaction‚ we were able to convert the liquid methyl oleate to solid crystals of methyl stearate. A mineral oil was also used to bubbler was used to maintain the hydrogen pressure slightly above the atmospheric pressure and to prevent back-diffusion
