Term | Definition |
---|---|
mole ratio | the ratio of moles of one substance to moles of another substance in a balanced chemical equation |
stoichiometry | the process of using a balanced chemical equation to determine the relative masses of reactants and products involved in a reaction |
stoichiometric mixture | a mixture that contains the relative amounts of reactants that matches the numbers in the balanced equation |
limiting reactant | the reactant that is completely used up when a reaction is run to completion |
limiting reagent | MEANS LIMITING REACTANT |
theoretical yield | the maximum amount of a given product that can be formed when the limiting reactant is completely consumed |
percent yield | the actual yield of a product as the percentage of the theoretical yield |
actual yield | amount of product recovered when the reaction is performed in the laboratory |
excess reactant | a quantity of a reactant that is present in sufficient quantity such that some remains after the reaction is complete |
coefficients | reveal the mole ratios of the substance in a balanced equation |
balanced chemical equation | verifies the law of conservation of matter |
percent yield equation | actual yield/theoretical yield x100 |
