Document Summary
A chemical reaction is a change in which: atoms rearrange, old bonds are broken and new bonds are formed, one or more new substances form. Example: hydrogen burns in air forming water: heat energy is either given off or taken in. Chemical equations: describe chemical reaction, describe how elements can combine to form compounds. 4 al + 3 o2 2 al2o3 (sapphire: describe how compounds transform into other compounds (more common) or into elements. 2 h2o2 2 h2o + o2: depict the kind of reactants and products and their relative amounts in a reaction. Stoichiometry is the study of the quantitative aspects of chemical reactions. Ina given reaction, there may not be enough of one reagent to use up the other reagent completely. The reagent in short supply limits the quantity of product that can be formed. The quantitative study of the rates of chemical reactions and the factors upon which chemical reactions depend.
