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)
