Question

12. Give two uses of oxygen gas and nitrogen gas present in the air.​

Answer 1

Answer:

Oxygen:- Common uses of oxygen include production of steel, plastics and textiles, brazing, welding and cutting of steels and other metals, rocket propellant, oxygen therapy, and life support systems in aircraft, submarines, spaceflight and diving.

Nitrogen:- Nitrogen is important to the chemical industry. It is used to make fertilizers, nitric acid, nylon, dyes and explosives. To make these products, nitrogen must first be reacted with hydrogen to produce ammonia. This is done by the Haber process.

Its inertness is fundamental to its other major uses, for example, to provide an inert atmosphere when welding metals (to prevent metals reacting with air to form oxides and nitrides). It is also used to purge gas from tanks which have contained fuels such as liquid hydrogen.

Due to these properties, the nitrogen is used in food industry, steel processing, electronics and similar applications. Oxygen is also without colour, odour and taste. Compared to nitrogen the oxygen reacts with most of the chemical elements. It is necessary for most living organisms for metabolic processes.
