Importance of Chemistry Chemistry is an important branch of science. Chemistry deals with the matter that form our environment and the transformation that the matter undergoes. Chemistry is therefore‚ useful in understanding the changes taking place in the constituents of the environment and the resulting advantages. Chemistry is connected with composition‚ structure and properties of the matter. In fact it is a science of atoms and molecules. Organic chemistry‚ inorganic chemistry‚ physical chemistry‚ analytical

Sustainable Chemistry Terry Collins* Chemistry has an important role to play in achieving a sustainable civilization on Earth. The present economy remains utterly dependent on a massive inward flow of natural resources that includes vast amounts of nonrenewables. This is followed by a reverse flow of economically spent matter back to the ecosphere. Chemical sustainability problems are determined largely by these economy-ecosphere materials flows (see the figure‚ below)‚ which current chemistry education

Chemistry and Society Chemistry 110 March 17‚ 2012 Introduction Chemistry is very important in our lives even though we may not realize that chemistry is everywhere. This paper serves to examine the ways in which chemistry is relevant in everyday life and in society. It will also examine the difference between accuracy and precision and provide examples of when accuracy and precision are crucial in measurements and why society depends on these measurements to be accurate and precise ( Tam

If We Had Known About Green Chemistry In 1951‚ How Would Things Be Different Today? Green Chemistry is the making of chemical products that reduces or eliminates the use and production of hazardous substances in the designing‚ making‚ and use of chemical products. It involves the designing and re-designing of chemical creation and chemical products to prevent pollution which will therefore solve environmental problems. Green Chemistry is environmentally safe and has very little side effects on

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

Prehistoric Times - Beginning of the Christian Era (Black Magic) * 1700 BC King Hammurabi’s reign over Babylon In ancient Babylon King Hammmurabbi began to classify metals such as gold ‚ iron‚ and copper. He also gave certain materials higher value than others‚ depending on the potential of the material. Known metals were recorded and listed in conjunction with heavenly bodies. 430 BC Democritus of ancient Greece Democritus and the atom: c.420 BC In the late 5th century BC Democritus
