Which of the following is NOT true about percent yield?
Percent yield is often less than 100%
Percent yields measures the efficiency of a reaction carried out in a lab
Percent yield of 100% is unlikely when reactants or products were no carefully measured
Percent yield is the ratio of theoretical yield to actual yield expressed as a percent

Respuesta :

The percent yield of a reaction measures the reaction's efficiency.
It is the ratio between the actual yield and the theoretical yield.

The theoretical yield for a reaction is calculated based on the limiting reagent. This allows researchers to determine how much product can actually be formed based on the reagents present at the beginning of the reaction.

The correct answer is D. Percent yield is the ratio of theoretical yield to actual yield expressed as a percent

Hope this helped!
