Answer
Theoretical yield is how much (in either grams or moles, etc.) product would be formed if ALL of the reactants reacted fully to form products as specified by the balanced equation. Actual yield is how much (found experimentally) is actually produced by the reaction (also in grams or moles, etc.). Percent yield is a calculation by taking Actual yield/Theoretical Yield * 100%
