Answer:

D. 2NH₃(g) ⟶ N₂(g) + 3H₂(g)

Explanation:

A chemical equation must show the correct formulas for reactants and products.

A and B are wrong, because they have NH₃ as a product.

C is wrong. H₃ does not exist.

A is correct. The equation for the decomposition of ammonia is

2NH₃(g) ⟶ N₂(g) + 3H₂(g)
