In the balance chemical reaction 282 + 02 -- 2H2, what does the law of conservation of mass indicate about the reactants and products

Question

In the balance chemical reaction 282 + 02 --> 2H2, what does the law of conservation of mass indicate about the reactants and products
A. The total mass of the reactants is greater than the total mass of the products
B. The total mass of the reactants is equal to the total mass of the products
C. The total mass of the reactants can change during the reaction
D. They reaction produces more mass than is present in the reactants

GPT-4o mini · Answer

The correct answer is: **B. The total mass of the reactants is equal to the total mass of the products.** The law of conservation of mass states that in a closed system, mass cannot be created or destroyed during a chemical reaction. This means that the total mass of the reactants must equal the total mass of the products.
