Question

Classify each of the reactants as a limiting reactant or an excess reactant for a reaction starting with five moles of each reactant. drag the appropriate items to their respective bins.

Answer 1

In order to determine if a reactant is in excess or limiting, we must first know the required amount of reactants. This is referred to as the stoichometric amount of reactant, and it is obtained from the chemical equation.
From the equation, we form a ratio of the reactants. The reactant supplied in excess of that ratio is the excess reactant, while the other is the limiting reactant.
