If the total product formed is 36 grams and one reactant was 11 grams what was the other reactant?

Answer and explanation

Correct answer: 25 grams

The governing concept is the law of conservation of mass: in a reaction carried out without loss of material, the total mass of reactants equals the total mass of products. Let the unknown reactant mass be x. Then 11 g + x = 36 g. Subtracting 11 g from both sides gives x = 36 − 11 = 25 g. Therefore, option B is correct. Option A simply repeats the known mass, option C gives the entire product mass rather than the missing reactant, and option D results from an incorrect subtraction. This calculation assumes the stated masses represent the complete reacting substances.
