Answer 1

The Law of Conservation of Mass states that the total mass of the substances before the reaction has to equal the total mass of the substances after the reaction. Atoms are not created or destroyed during a chemical reaction, and they are not transformed into different elements.

In the given reaction, N₂ reacts with 3H₂ to form 2NH₃. According to the Law of Conservation of Mass, the total mass of the nitrogen and hydrogen atoms before the reaction must be equal to the total mass of the nitrogen and hydrogen atoms after the reaction.
