Question

Enlist the use of Nitrogen.

Answer 1

Uses of Nitrogen($\mathrm{N}$):

• It is used in the manufacture of Ammonia(${\mathrm{NH}}_3$), to produce nitric acid, and subsequently used as a fertilizer.
• Nitric acid salts include important compounds like Potassium nitrate(${\mathrm{KNO}}_3$), Ammonium nitrate(${\mathrm{NH}}_4{\mathrm{NO}}_3$), and Nitric acid(${\mathrm{HNO}}_3$). Nitrated organic compounds such as nitro-glycerine are often explosives.
• Liquid Nitrogen is utilized as a refrigerant for transporting foodstuff and freezing purposes. Preservation of bodies and reproductive cells and stable storage of biological samples also makes use of liquid nitrogen.
• Nitrogen makes up 78 percent of the Earth‘s atmosphere and is a part of all living tissue. Nitrogen is a crucial ingredient of life since it is a constituent of DNA and as such is part of the genetic code.
• Nitrogen molecules often exist in the soil. Nitrogen can be present in Nitrates(${\mathrm{NO}}_3^{-}$) and Nitrites(${\mathrm{NO}}_2^{-}$) in water and in soils. These compounds are all part of the nitrogen cycle and both are interconnected.
