Limiting Reactants: 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: substance that is not used up completely in a reaction

When solving problems with chemical reactions and converting grams to moles/ moles to grams/ etc., set up a single equation so that you only round once.
