Final answer:
To determine the limiting and excess reactants in a stoichiometry problem, the same stoichiometric factors derived from the balanced chemical equation are used for all reactants to calculate the mass of products formed.
Step-by-step explanation:
To solve for limiting and excess reactants, you will repeat the same stoichiometry steps using the same stoichiometric factors derived from the chemical reaction for all reactants. When performing stoichiometry problems, you first need to use stoichiometry for each individual reactant to find the mass of the product produced.
The reactant that produces the lesser amount of product is identified as the limiting reactant, as it limits the extent of the reaction. The reactant producing a larger amount of product is the excess reactant, meaning that not all of it will react and some will be left over once the reaction is complete.
To find the amount of the remaining excess reactant, you would subtract the mass of the excess reactant that was consumed from the total initial mass of the excess reactant.
