| Stoichiometry | the calculation of the quantities of chemical elements or compounds involved in chemical reactions. |
| Limiting reagent | any reactant that is used up first in a chemical reaction |
| Excess reagent | a reagent present in a quanity that is more than sufficient to react with a limiting reagent |
| Theoretical yield | the amount of product that could form during a reaction calculated from a balanced chemical equation |
| Actual yield | the amount of product that forms when a ractio is carried out in the laboratory |
| Percent yield | the ratio of the actual yield to the theoretical yield for a chemical reaction expressed as a percentage |
