Chemistry 12 Unit 1 - Reaction Kinetics Chemistry 12 Worksheet 1-3 - Reaction Mechanisms 1. It is known that compounds called chlorofluorocarbons (C.F.C.s) (eg. CFCl3) will break up in the presence of ultraviolet radiation‚ such as found in the upper atmosphere‚ forming single chlorine atoms: CFCl3 CFCl2 + Cl The Cl atoms then react with Ozone (O3) as outlined in the following mechanism. Step 1: Step 2: Cl + O3 ClO + O2 ClO + O Cl + O2 (single "O" atoms occur naturally in the atmosphere

Biology Essay Genetic Engineering‚ also called Genetic Modification‚ is the direct manipulation of an organism’s genome using biotechnology. An organism that is generated through genetic engineering is considered to be a genetically modified organism (GMO). Humans have altered the genomes of species for thousands of years through artificial selection and more recently mutagenesis. Genetic Engineering as the direct manipulation of DNA by humans outside breeding and mutations has only existed

A computer is a machine that is able to take information (input)‚ do some work on or make changes to the information‚ to make new information (output). Computers have existed for much of human history. Examples of early computers are the astrolabe and the abacus. Modern computers are very different from early computers. They are now very powerful machines that are able to do billions of calculations every second. Most people have used a personal computer in their home or at work. Computers are
