Question

ammonia (nh₃) decomposes into its elements. predict the formulae of the two products of the reaction. tap to select or deselect answer. n₂ and h₂ nh and h₂ n and h₃ n₂ and h₃ n and h₂

Explanation:

Ammonia ($\ce{NH_3}$) is composed of nitrogen (N) and hydrogen (H) elements. When a compound decomposes into its elements, the elements exist in their diatomic forms (for non - noble gas elements like N and H). Nitrogen exists as $\ce{N_2}$ (diatomic molecule) and hydrogen exists as $\ce{H_2}$ (diatomic molecule). So the decomposition reaction of ammonia into its elements will produce $\ce{N_2}$ and $\ce{H_2}$.

Answer:

A. $\ce{N_2}$ and $\ce{H_2}$
