These oxides dissolve in water to give nitric and nitrous acids and fall on land along with rain. These are then utilised by different life- forms. The chemical fertiliser factories produce ammonia by combining hydrogen and atmospheric nitrogen under high pressure and temperature. This process is called industrial nitrogen fixation.
