Describe the chemical reaction based on the chemical equation

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.

answer : one can design an experiment using a liquid and an additive that can be added to the liquid and observe the chemical changes in the reaction species.

one would need a beaker which is filled with a known amount of the liquid in which thermometer is placed to measure the temperature changes; after addition of the additive to the liquid solution one can note down the temperature change and find whether the reaction is endothermic or exothermic in nature. by subtracting the initial temperature value with the final temperature one can find the temperature changes.

various combinations of liquid and additive can be used. liquid in this case can be a known quantity of water and additives can be epsom salt or without epsom salt the experiment can be conducted to notice the changes. water and ice, hydrogen peroxide and dry yeast, vinegar and baking soda,etc.
