ORGANIC CHEMISTRY LAB 2: Separation of Organic Liquid Mixtures Introduction: In this experiment‚ a mixture of two compounds‚ cyclohexane and toluene‚ was separated into fractions by the techniques of simple and fractional distillation. The individual fractions that were gathered from the distillation were analyzed using gas chromatography (GC) and used to compare the efficiencies of the two different distillation techniques. The ultimate goal of this experiment was to determine whether simple

Lastly‚ there is disease which is the most important effect from factory farming it can have a big impact on the consumers and the animal. One of the many diseases is mad cow diseases it is also known as Bovine spongiform encephalopathy (BSE) is said to be caused by feeding dead cows to other cows; the cow becomes infected and so can humans through the consumption of diseased meat (O’Brien 30). There is something that has to change they could either stop feeding dead cows to cows which they definitely

The industry is growing rapidly since the past five years and has caught the attention of farmers‚ manufacturers and‚ above all‚ consumers. The health benefits of organic food are more perceived than real. However‚ the public opinion that organic food is healthier than

Legal protection and conservation plan for these endangered subspecies should be established. However‚ organic evolution has been taking place for 3.5 billion years. It is impossible to study every living organism from an individual level. Biologists group and classify living and extinct organisms for many reasons such as to establish a common language or
