Effects of Alcohol Essay

It was hypothesised that the longer the carbon chain of an alcohol the more energy output would be released and a longer flame length will be produced due to the extra carbon-carbon and carbon-hydrogen bonds. As the wick length increases so does the flame length and therefore more energy output will be produced. The data collected throughout the course of the three experiments partially supports the hypotheses. However, the results gathered when testing how the length of the carbon chain affects…

Christ as my Lord and Savior and gave me a foundation to build my future goals upon. This event included a mixture of drugs, alcohol, parties, and prisons. It started when I was fifteen and my step-father, the man who raised me, passed away. It was at this point that I tried marijuana for the first time. The next week I took my first narcotic pill, while also drinking alcohol. This started off a quick downward spiral,…

Results: Figure 1; Repellent activity in percentage of the volatile extract of C. sinensis, C. limon, C. aurantifolia and positive control on Camponotus nearcticus. The activity was generally high on C. nearcticus with positive control recording 100% activity, C. limon having 95% and C. sinensis having the lowest activity of 82.5% activity. Figure 2; Observed percentage lethal activity of the volatile extracts on C. nearcticus at five concentration points after 180 minutes of exposure…

Maci Mullins CHEM2130-001 12/8/2017 A Wittig Reaction of trans-Cinnamaldehyde Statement of Question: What is the stereochemistry in the Wittig product, and why is it formed? Hypothesis: There were two possible stereochemical outcomes for this experiment, either cis, (E,Z), or trans, (E,E). The cis product, (E,Z), would form if the double bond and phenyl group added to the same side. The trans product, E,E), would form if the double bond and phenyl group were to add to the opposite sides.…

Aims of Experiment 1. To extract benzoic acid from the toluene-benzoic acid mixture, using oxidation-reduction reaction (chemical properties) and difference of solubility (physical properties) –Expt. 1 2. To learn how to recrystallize the solid organic compounds well for getting more purified compounds –Expt. 2 3. To find which differences between raw product and recrystallized product are observed. –Expt. 2 4. To determine melting point range of organic compounds with digital melting point…

Majority of teens continue to consume alcohol. (Evidence: According to the Columbia University, “a minimum of $22.5 billion (17.5 percent) of consumer expenditures for alcohol came from underage drinking”.) 2. Subpoint: The MLDA 21 promotes Vandalism. (Evidence: According to Marl Kleiman, a professor that teaches at NYU and had its education at Harvard university says that, MLDA 21 encourages young adults to acquire and use false identification documents to procure alcohol. In this era of…

In Experiment 12B we used an umpolung reagent in an umpolung synthesis to synthesize benzoin from benzaldehyde. Umpolung synthesis is a synthetic approach that allows us to switch the identity of a reacting species. For example, the normal chemical reactivity of a nucleophile can be switched to one of an electrophilic compound. Two common agents are cyanide and thiamine (Vitamin B). The mechanisms for both agents are the same. In this experiment, thiamine was used to turn benzaldehyde, an…

floats in giant lumped up bubbles. Well there is much more than meets the eye in thermometers. For many, questioning things as a child is just a natural thing. For adults it becomes just something that is accepted, but their is many things that go into effect to make Mercury what it is. The book “The Disappearing Spoon”, by Sam Kean is a book that gives an explanation of basic chemistry. It does a great job informing the readers of how chemistry was literally discovered by only a handful of…
