Nitrogen gas (n2) and hydrogen gas (h2) combine to form ammonia (nh3).
which equation correctly represents the reaction?

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.

To balance this equation, we need to a multiply by 3 on reactant side, And, we also need to multiply by 2.

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