Answer:
Step-by-step explanation:
Chemical equation:
NH₃ + O₂ → NO + H₂O
The given reaction shows the formation of nitric oxide and water from ammonia and dioxygen in the presence of catalyst Pt. The catalyst speed up the reaction. This reaction is double displacement reaction.
The given equation is not balanced. That's why this reaction not follow the law of conservation of mass. Balanced equation is given below.
Balanced chemical equation:
4NH₃(g) + 5O₂(g) → 4NO(g) + 6H₂O(l)
This is the balanced equation. This follow the law of conservation of mass.
Law of conservation of mass:
According to the law of conservation mass, mass can neither be created nor destroyed in a chemical equation.
There are four nitrogen, ten oxygen and twelve hydrogen atoms are present on both sides of equation.
