With whom the ammonia reacts, write down the equations of possible reactions.

Ammonia is a colorless gas with a pungent, suffocating odor. It dissolves readily in water to form ammonium hydroxide solution, which can cause irritation and burns. Ammonia gas is easily compressed and forms a clear, colorless liquid under pressure.

In the laboratory, ammonia is best synthesized by hydrolysis in the form of metal nitride: Mg 3 N 2 + 6H 2 O → 2NH 3 + 3Mg (OH) 2.

Combustion of ammonia proceeds with difficulty, but in its process nitrogen, gas and water are obtained: 4NH 3 + 3O 2 + heat → 2N 2 + 6H 2 O.

Ammonia readily dissolves in water, releasing heat: NH 3 + H 2 O ⇌ NH 4 + + OH -.
