Describe the mass of the reactants and products given the balanced chemical reaction. a. the mass of the products is 2/3 that of the reactants. b. the mass of the reactants equals the mass of the products. c. the mass of the reactants is less than the mass of the products. d. the mass of the reactants is greater than the mass of the products.

The correct answer is option (b).

Explanation:

Law of Conservation of Mass states that ' in a chemical reaction mass can neither be created nor be destroyed' .

In balanced chemical reaction the total mass of the reactants is equal to the total mass of the products formed.

According to the law of conservation of the mass the correct answer from the given options is option (b). that ".the mass of the reactants equals the mass of the products."

Hence, the option (b) is correct.

the molecules move in straight line until they collide with each other or with the walls of the container. collisions are perfectly elastic; when two molecules collide, they change their directions and kinetic energies, but the total kinetic energy is conserved.
