| activity series of metals | a table listing the metals in order of decreasing activity |
| balanced equation | a chemical equation in which mass is conserved, each side of the equation has the same number of atoms of each element |
| catalyst | a substance that increases the rate of reaction by lowering the activation-energy barrier; it itself is not used up in the reaction |
| chemical equation | an expression representing a chemical reaction |
| coefficient | a small whole number that appears in front of a formula in a balanced chemical equation |
| chemical reaction | the changing of substances to other substances by the breaking of bonds in reactants and the formation of bonds in the products |
| combination (synthesis) reaction | a chemical change in which two or more substances react to form a single new substance |
| combustion reaction | a chemical change in which oxygen reacts with another substance, often producing energy in the form of heat and light |
| complete ionic equation | an equation for a reaction in solution showing all strong electrolytes as ions |
| decomposition reaction | a chemical change in which a single compound is broken down into two or more simpler products |
| double-replacement reaction | a chemical change that involves an exchange of positive ions between two compounds |
| net ionic equation | an equation for a reaction in solution showing only those particles that are directly involved |
| single-replacement reaction | a chemical change in which one element replaces a second element in a compound |
| spectator ion | an ion that is not directly involved in a chemical reaction |
