Question

The chemical equations are balanced to satisfy one of the following laws in chemical reactions. This law is known as
(a) law of conservation of momentum
(b) law of conservation of mass
(c) law of conservation of motion
(d) law of conservation of magnetism

Answer 1

The chemical equations are balanced to satisfy the:

(b) law of conservation of mass .

- This law states that whenever matter undergoes a chemical change, the total mass of the products is the same as the total mass of the reactants.

- Thus, according to this law, the mass of products in a reaction must be equal to the mass of reactants.

- So the equations are balanced to obey this law.

Answer 2

Answer:

(b) law of conservation of mass

Explanation:

The Law of conservation of mass states that matter can be changed from one form into another, mixtures can be separated or made, and pure substances can be decomposed, but the total amount of mass remains constant. We can state this important law in another way. The total mass of the universe is constant within measurable limits; whenever matter undergoes a change, the total mass of the products of the change is, within measurable limits, the same as the total mass of the reactants
