| A | B |
| Mole Ratio | a conversion factor that is created by the Balanced Chemical equation that relates the amount of moles of any two substances |
| Composition Stoichiometry | the mass relationships of the elements in a COMPOUND |
| Reaction Stoichiometry | mass relationships between reactants and products in a CHEMICAL REACTION |
| Actual Yield | the measured amount of a product from a chemical reaction |
| Theoretical Yield | the maximum amount of product that can be produced according to the balanced chemical equation |
| Excess Reactant | the reactant in a chemical reaction that is NOT used up in the reaction |
| Limiting Reactant | the reactant that will be entirely used up in the reaction thus Limiting the product produced |
| Percent Yield | the ratio of the actual yield to the theoretical yield. This number is then multiplied by 100 to get into percent |
| Activity Series List | a list of metals according to their ability to react in an reaction. The most reactive are listed at the top of the list. Used to determine if a reaction will take place in single replacement reactions |
| Molar Mass | the mass of a molecule or compound when there are 6.02 e23 molecules or atoms present |
