The following questions refer to “Empirical Formula of Copper Chloride”. What is a limiting reactant? What is the theoretical yield? The reactant that is completely consumed in a chemical reaction limits the amount of products formed and is called the limiting reactant, or limiting reagent. The calculated quantity of product in a reaction is called the theoretical yield of the reaction. Chem 171 Quiz 3 Version A (Key Chrom/Emp) 1.
