The purpose of this experiment is to synthesize isopentyl ester by an esterification reaction between a carboxylic acid and an ester. Carboxylic esters‚ like isopentyl acetate‚ are normally used to create artificial flavors. In the preparation of isopentyl acetate‚ esterification of acetic acid and isopentyl alcohol occurs. Esterification is an equilibrium shift to the product side using an excess of one of the starting components. In this experiment‚ the excess reagent is acetic acid because it

Animal Testing: contradictory perspectives and the balance between them A long time ago‚ animals were used for numerous purposes‚ and one of those uses is utilising them in scientific studies which known as "Animal Testing". According to Oxford dictionaries‚ animal testing refers to experiments involving the use of animals. As reported by the national centre for biotechnology information (2011)‚ animals were used regularly in scientific biomedical researches in the past by Greek and Arab physician

Throughout history animal testing has played an important role in leading to new discoveries and human benefit. However‚ the realization of the moral status that animals hold only began in the late 1970’s. Today it is a multibillion dollar industry that involves several institutions‚ cosmetic companies and scientific centers. What people tend to forget is the great number of animal subjects that have suffered serious harm during the process of experimentation. Many ethical questions arise about these

Synthesis of Information In summary‚ the articles researched were divided into four main categories. The categories all focused on something different. The categories were; the perception kids have on food‚ communities raising healthy kids‚ nutritional awareness and the school context. The first two articles had the common theme of how children view food and to find what children thought and felt about healthy food. The third article was aimed towards parents. The theme of this article was how

Animal Testing Animal testing or animal experimentation is the use of non-humans in experiments conducted inside of universities‚ medical schools and pharmaceutical and commercial facilities. The researchers study genetics‚ toxicity testing and cosmetic testing also animals are breezed for education and defense research. Animal testing should not be continued because the tests put animal through pain‚ some tests do not even work and there are alternative which protect animals that can be used instead
