| combustion reaction | the complete reaction of a hydrocarbon with oxygen to produce carbon dioxide and water |
| decomposition reaction | a single compound is broken down into two or more products |
| catalyst | a substance that speeds up the rate of a chemical reaction |
| reactants | the elements or compounds on the left side of a chemical equation before the arrow |
| single replacement reaction | reaction in which atoms of one element replace the atoms of a second, less reactive, element in a compound |
| balanced equation | a chemical equation that is consistent with the law of conservation of mass |
| coefficients | numbers placed in front of chemical symbols or formulas in a chemical reaction |
| chemical equation | a representation of a chemical reaction with formulas of reactants to the left of an arrow and the formulas of the products to the right of an arrow |
| synthesis (combination) reaction | chemical change in which two or more substances react to form a single new substance |
| double replacement reaction | chemical change involving an exchange of positive ions between two compounds |
| products | the elements or compounds on the right side of a chemical equation after the arrow |
| (g) | designates a product or reactant that is in the gaseous state |
