Answer :
The physically impossible value for the actual yield, in this case, is D. 110 grams. This is because the actual yield cannot exceed the theoretical yield of 100 grams for a reaction.
The theoretical yield is the maximum amount of product that can be formed based on the amount of limiting reactant present in a reaction. It is calculated using stoichiometry, which involves the use of mole ratios between the reactants and products in a chemical reaction. It is the yield calculated from the balanced chemical equation that is determined using stoichiometry.
The actual yield is the amount of product actually obtained from a chemical reaction. It is obtained experimentally by performing the reaction in the lab and measuring the amount of product obtained. It is always lower than the theoretical yield because of the limitations of the reaction, such as incomplete reactions, side reactions, and loss of product due to handling or impurities.
The relationship between theoretical yield and actual yield is given by the percent yield. It is calculated as the ratio of actual yield to theoretical yield, multiplied by 100. The percent yield is a measure of the efficiency of the reaction and is always less than 100%. It is physically impossible for the actual yield to be greater than the theoretical yield because the theoretical yield is the maximum amount of product that can be formed in a reaction. Therefore, the correct answer is D. 110 grams.
