Answer:
The equation you provided is an example of a chemical reaction in which nitrogen gas (N2) and hydrogen gas (H2) react to form ammonia (NH3). The Law of Conservation of Mass states that matter cannot be created or destroyed, only transformed from one form to another.
In this reaction, the total number of atoms on the reactant side (left side of the arrow) is equal to the total number of atoms on the product side (right side of the arrow). Specifically, there are 2 nitrogen atoms, 6 hydrogen atoms, and 2 ammonia molecules on the reactant side, and these atoms are rearranged to form 2 nitrogen atoms, 6 hydrogen atoms, and 2 ammonia molecules on the product side.
This demonstrates that the total mass of the reactants is equal to the total mass of the products, which is a key principle of the Law of Conservation of Mass. This law is a fundamental concept in chemistry that helps us understand how chemical reactions take place and how atoms are transformed from one form to another.
