Which chemical formula represents ammonia?

Explanation:
The main idea is recognizing how a chemical formula shows which elements and how many atoms are present. Ammonia consists of one nitrogen atom bonded to three hydrogen atoms, so its formula is NH3. The other common compounds have different compositions: water is H2O (two hydrogens, one oxygen), hydrogen chloride is HCl, and methane is CH4 (one carbon, four hydrogens).
