Loss of reactants through transfer

Explanation:

Answer 2

Percent yield is the ratio between actual and theoretical yield multiplied by 100%. The higher the actual yield the higher is the percent yield. In the percent yield there is always a limiting reagent that creates the difference between what is obtained and what is calculated. Percent yield can never exceed 100% if that happens it means that there was some error in the theoretical yield calculation.
