| Addition reaction | a chemical reaction in which two or more substances combine to form a new compound. |
| Combustion reaction | a reaction in which a substance combines with oxygen |
| Decomposition 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 in water to make an ionic solution. |
| 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 |
| Single-displacement reaction | a reaction in which one element replaces a similar element in a compound. |
