The Synthesis of Alkenes: The Dehydration of Cyclohexanol Adam Ohnmacht CHEM 0330 Scott Caplan 10/30/12 Abstract: In Organic Chemistry‚ many different methods are used to synthesize organic compounds from various components. In this lab‚ cyclohexanol was dehydrated to cyclohexene through an elimination reaction. In order to separate the cyclohexene product from the cyclohexanol starting component‚ previously learned lab techniques such as extractions and simple distillation were used.

Homeostatic Control of Core Body Temperature Our bodies have processes that happen to keep everything at an even rate. If things get out of balance our bodies tries to bring them back into balance. Homeostasis refers to the processes of keeping internal body environment in a steady rate‚ when the external environment is changed. The aim of this essay is to discuss the internal environment‚ the importance of regulation of core temperature‚ negative feedback and positive feedback and contrast

Import-Export Imbalance: 1.- The negative trade is heavy and only counterbalanced by the service account surplus. 2.- Over the last two decades‚ Philippine exports have shifted from commodity-based products to manufactured goods. 3.- In the midst of the current global economic recession‚ the exports of electronics‚ garments and textiles are yet to reach a level of import neutralization. 4.- We can solve it by apply a tax directly to consumer and every one confront the problem in their money

IntroductionA dehydration reaction of an alcohol results in an alkene. This type of reaction requires an alcohol‚ an acid catalyst and heat. Generally strong concentrated acids‚ like sulfuric acid and phosphoric acid‚ are used as the acid catalyst.The acid catalyst protonates the alcohol‚ to make a much better leaving group. Weakest bases make the best leaving groups‚ so once the alcohol is protonated the leaving group leaves and produces in a carbocation and water. In order to form the double bond

Gender Imbalance In early imperial China‚ the way of life was very different than it is in China today. Men were known to have taken care of the fields. Women were to stay at home and to their woman’s work. Their work consisted of sewing‚ weaving‚ spinning‚ and embroidery. This is the Confucian way of how to be a good woman. Although‚ it was not necessary for these jobs to be done year- round; many women also had the job of tea picking. In that time‚ people believed that women who picked tea would

connection between different systems in the body and how they use water to maintain proper health and function. We will discuss what happens to the body when we intake too much water (water toxicity)‚ likewise when we lose or intake too little (dehydration). Why is water essential to health maintenance? Water is the “great regulator” in the body. It has several functions: to dissolve nutrients and move them throughout the body‚ to flush and carry waste particles from the body‚ and to

Describe two examples of homeostatic systems in humans The phrase homeostasis originates from the Greek language. “Homeo” defined as “similar” and “stasis” meaning “stable”. Homeostasis is vital for us humans as it maintains equilibrium in the body‚ which may be caused due to extrinsic changes. Homeostasis happens to sustain the bodies activity‚ health and functioning. Homeostasis can occur to organs like skin‚ kidney or liver and it usually contains a system of feedback controls. The body has various

A 5 year old girl Jenny has presented to the Emergency Department with her mother‚ she is suffering from a variety of symptoms including wheezing and vomiting‚ a dry mouth‚ and a temperature of 39.7 degrees Celsius. Vomiting is when the person is excreting all food from there stomach via the mouth using forces from the oesophagus and stomach (Hockenberry & Wilson‚ 2007). The rationale for choosing this symptom is that vomiting is a clear sign that the body is trying to get rid of a pathogen‚ with

Body fluids are maintained at a constant level by several homeostatic mechanisms: Osmosis- is the diffusion of water through a selectively permeable membrane known as a plasma membrane. Water is highly polar it is repelled by the lipid core (nonpolar) of the plasma membrane but can easily pass through the aquaporins created by the proteins in the membrane‚ so osmosis is happening all the time as water moves into and out of cells. Diffusion- Is where ions move away from an area where they are
