Dehydration of Methylcyclohexanols Balie Zander Date Conducted: March 27‚ 2013 Date Submitted: April 3‚ 2013 Introduction: The purpose of this experiment was to demonstrate the application of Zaitzev’s rule‚ the Evelyn Effect and the occurrence of an E1 mechanism in an alcohol dehydration reaction. Specifically this experiment involved the dehydration of 2-methylcylcohexanol by heating this alcohol in the presence of phosphoric acid and then to based on the results of the gas chromatography

Homeostasis: An Analogy Reginald Robinson BIO1000 Capella University The homeostatic mechanism that regulates body temperature is called hypothalamus. It senses when your body’s temperature is too hot or cold. When your body is too hot‚ the hypothalamus senses that a change needs to be made so to reverse the heating process‚ thus reducing the amount of blood that is being sent to that area. This same action will cool the body and return it to a normal temperature. The ways in which

Dehydration of 2-Methylcyclohexanol February 10‚ 2013 Introduction This experiment was done to demonstrate the practical use of dehydration reactions and produce three different products. Dehydration reactions are reactions that involve the leaving of an “-OH” or “-H” group resulting in the formation of a double bond between two carbons. For the experiment we used 2-Methylcyclohexanol as a beginning reagent to dehydrate and possibly form 3-methylcyclohexene‚ 1-methylcyclohexene‚ or methylenecyclohexane

Exercise on Homeostasis Hypothesis: If a human being walks up and down a set of stairs for eight minutes with a set rest every two minutes‚ the body will present such changes as heart and breathing rates‚ perspiration level‚ body color and temperature because of the response of the body to change whilst exercising. Discussion Questions 1. What are the changes you observed in body color and perspiration level in response to? How do these changes contribute to the maintenance of homeostasis? The

“Calcium Homeostasis” Kayla Smith Anatomy and Physiology I BSC 1085C Ref# 82458 Calcium plays a very significant role in our bodies. Approximately 99 percent of the calcium in our bodies is stored in the teeth and bones. Calcium generates about two percent of our total body weight. Calcium is crucial in bone formation‚ keeping strong bones and teeth and is known for helping to prevent osteoporosis. Although calcium is mostly thought about in the bones and teeth‚ it also plays important roles

Dehydration Sci/241 Abbe Breiter-Fineberg 4/1/2012 Passing out‚ lethargy‚ constipation‚ dry mouth and even dry eyes are very few symptoms in the long list of signs to tell us that we are dehydrated. Being dehydrated is potentially very bad and if not taken care of a person can end up in the hospital or even dying. Many things can cause dehydration including drinking too much alcohol or simply not drinking enough water. Without ample amounts of water our bodies cannot function correctly‚
