| addition reaction | a chemical reaction in which two or more substances combine to form a new compund |
| combustion reaction | a reaction in which a substance combines with oxygen, releasing large amounts of energy in the form of heat and light |
| decompostion reaction | a chemical reaction in which a single compound is broken down to produce two or more smaller compounds |
| dissolution reaction | a reaction that occurs when an ionic compound dissolves throughout a solvent |
| double-displacement reaction | a reaction in which ions from two compounds in a solution exchange places to produce two new compounds |
| endothermic reaction | a reaction in which more energy is required to break the bonds in reactants than is released from the formation of new bonds in the products |
| exothermic reaction | occurs when less energy is required to break the bonds in reactants than is released when bonds are formed to make new products |
| insoluble | a term to describe a substance that does not dissolve in water |
| polymerization | the production of a very large molecule by a series of synthesis reactions |
| precipitate | substance formed when one of the compounds in a double-displacement reaction is insoluble, or does not dissolve in water |
| single-displacement reaction | a reaction in which one element replaces a similar element in a compound |
