| actual yield | the amount of product formed when a reaction is carried out in the laboratory |
| percent yield | the ratio of the actual yield to the theoretical yeild |
| theoretical yield | the calculated amount of product formed during a reaction |
| excess reagent | quantity of a reactant that is more than enough to react with a limiting reagent |
| limiting reagent | the reactant that determines the amount of product that can be formed in a reaction |
| product | a new substance formed in a chemical reaction |
| reactant | a starting substance in a chemical reaction |
| chemical equation | a concise representation of a chemical reaction |
| skeleton equation | a chemical equation that does not indicate relative amounts of reactants and products |
