Explanation:
Law of conservation of matter or energy states that energy can neither be created nor it can be destroyed. It can only be transformed from one form to another.
Similarly, matter cannot be created or destroyed as mass will always remain constant irrespective of changes in the state of matter.
In the given reaction, [tex]N_{2} + 8H \rightarrow 2NH_{3} + H_{2}[/tex], we can see that the number of reactant species equal to the number of product species.
Hence, it follows law of conservation of matter and energy.
