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

reactants to the product. To think of stoichiometry outside of chemistry‚ imagine a bookshelf. To assemble the bookshelf you may need 3 planks of wood‚ 1 giant plank of wood‚ and 20 nails. Even though the amount of the reactants is high‚ the product would be only one bookshelf. Stoichiometry is basically studying the relations between the reactants (in this case the pieces) and the product (bookshelf). As we learned in class‚ Stoichiometry uses a number of equations and constants. Namely‚ the Avogadro

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 )
