#ExplanationThe question refers to a chemical reaction where the conditions before and after the reaction are given. The law that is applicable to such a scenario is the Law of Conservation of Mass. This law states that for any system closed to all transfers of matter and energy, the mass of the system must remain constant over time, as system mass cannot change quantity if it is not added or removed. Hence, the quantity of mass is conserved over time. The law implies that mass can neither be created nor destroyed, although it may be rearranged in space and changed into different types of particles; and that for any chemical process in a closed system, the mass of the reactants must equal the mass of the products.#Answerlaw of conservation of mass
