The excess reactant is the reactant which remains when all the other reactants have been used up. The reactant that gets used up first in a chemical reaction is the limiting reactant, also known as the limiting reagent. If calcium is reacting with sulfuric acid, and you observe there are bubbles of hydrogen gas given off which then stop, and the calcium is still there, calcium is in excess, and sulfuric acid is the limiting reactant.
