The formula for ammonia gas is NH3. Its appearance is a colorless gas.
Ammonia gas is formed by the balanced chemical reaction between nitrogen and hydrogen elements. The balanced chemical equation for the formation of ammonia gas is as follows:
N2+3H => 2NH3
So, Nitrogen and Hydrogen are present in the ration of 2:6 or 1:3.
