Limiting Reactant and Percent Yield Which statement correctly describes the relationship between reactant and yield? The actual yield is calculated from the amount of the excess reactant present The actual yield is calculated from the amount of the limiting reactant present The theoretical yield is calculated from the amount of the excess reactant present. The theoretical yield is calculated from the amount of the limiting reactant present.

The correct statement is: "The actual yield is calculated from the amount of the limiting reactant present."<br /><br />In a chemical reaction, the limiting reactant is the reactant that is completely consumed first and determines the maximum amount of product that can be formed. The actual yield is the amount of product that is actually obtained from the reaction, which is determined by the amount of the limiting reactant present.<br /><br />The theoretical yield is the maximum amount of product that can be formed if the reaction were to go perfectly, with no losses or side reactions. The theoretical yield is calculated from the amount of the limiting reactant present, based on the stoichiometry of the balanced chemical equation.<br /><br />The excess reactant is the reactant that is not completely consumed in the reaction and is left over after the reaction is complete. The amount of excess reactant present does not determine the actual yield or the theoretical yield of the reaction.
