Question

ammonia is a covalent compound used in many cleaners. what is its chemical formula?
n₂o
h₂o
nh₃
ho₃

Explanation:

Ammonia is composed of nitrogen (N) and hydrogen (H). The chemical formula for ammonia is \(NH_3\). \(N_2O\) is nitrous oxide, \(H_2O\) is water, and \(HO_3\) is an incorrect formula as hydrogen typically has a +1 oxidation state and oxygen usually has -2, and this formula does not follow proper valency rules.

Answer:

C. \(NH_3\)
