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 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. The theoretical yield is the maximum amount of product that can be formed if the reaction were 100% efficient, and it is calculated from the amount of the limiting reactant present. The excess reactant is the reactant that is not completely consumed and is left over after the reaction is complete.
