Term | Definition |
---|---|
Composition stoichiometry | deals with the mass relationships of elements in compounds |
reaction stoichiometry | involves the mass relationship between reactants and products in a chemical reaction |
mole ratio | a conversion factor that relates the amounts in moles of any two substances involved in a chemical reaction |
limiting reactant | is the reactant that limits the amount of the other reactant that can combine and the amount of product that can form in a chemical reaction. |
excess reactant | the substance that is not used up completely in a reaction is called the excess reactant |
theoretical yield | is the maximum amount of product that can be produced from a given amount of reactant |
actual yield | the measured amount of a product obtained from a reaction is called the actual yield of that product |
percentage yield | the percentage yield is the ratio of the actual yield to the theoretical yield, multiplied by 100. |
