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 12 Unit 2 Notes - Equilibrium Chemistry 12 Tutorial 5 – The Equilibrium Constant (Keq) What is Keq ? The "K" in Keq stands for "Constant". The "eq" means that the reaction is at equilibrium. Very roughly‚ Keq tells you the ratio of Products/Reactants for a given reaction at equilibrium at a certain temperature. [Products] [Reactants] K eq = It’s not quite this simple when we deal with real substances. Let’s take an example. It has been found for the reaction: 2HI(g )

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
