In a closed container, 12 g of reactants completely undergo a reaction to form products, and no substance leaves the container. What will be the total mass of the products?
Answer and explanation
Correct answer: 12 g
According to the law of conservation of mass, mass is neither created nor destroyed in a chemical reaction. Since no substance leaves the closed container, the total mass of the products equals the total mass of the reactants. Therefore, the mass of the products is 12 g. The 24 g option is incorrect because a reaction does not double the mass.
