At room temperature, nitrogen is a very inactive gas. It does not combine with oxygen,hydrogen,or most other elements. Nitrogen will combine with oxygen, however, in the presence of lightning or a spark. The electrical energy from either of those sources causes nitrogen and oxygen to form nit...
synthetic ammoniaChemical plant for production of ammonia and nitrogen fertilizers.(more) The Haber-Bosch process directly synthesizes ammonia from nitrogen and hydrogen and is the most economical nitrogen-fixation process known. About 1909 the German chemist Fritz Haber ascertained that nitrogen from the...
Ammonia is produced by the reaction between nitrogen andHydrogen(Haber process). Ammonia is then used for fabrication of fertilizers, nitric acid (Ostwald process), nitro-glycerine (explosive). Liquid nitrogen Liquid nitrogen is used for freezing food products, preservation and storage of biological ...
Elemental nitrogen can be used as an inert atmosphere for reactions requiring the exclusion of oxygen and moisture. In the liquid state, nitrogen has valuable cryogenic applications; except for the gases hydrogen, methane, carbon monoxide, fluorine, and oxygen, practically all chemical substances have...
shielding of liquid hydrogen, helium, and neon; for the removal of skin blemishes in dermatology; and for shrink fitting of metal parts. Liquid nitrogen also has a number of classified applications in the missile and space programs of the United States, in which it is used in large ...
