Question

Nitrogen gas (N2) and hydrogen gas (H2) combine to form ammonia (NH3).

Answer 1

Answer 4.
N2 + 3H2 ---> 2NH3

Answer 2

Answer: Option (d) is the correct answer.

Explanation:

When nitrogen gas chemically reacts with hydrogen gas then it results in the formation of ammonia gas.

The chemical reaction equation for this will be as follows.

           $N_{2} + H_{2} \rightarrow NH_{3}$

To balance this equation, we need to a multiply $H_{2}$ by 3 on reactant side, And, we also need to multiply $NH_{3}$ by 2.

Therefore, the equation which will correctly represent this reaction will be as follows.

             $N_{2} + 3H_{2} \rightarrow 2NH_{3}$
