Multiple choice chemistry nitrogen and sulfur nitrogen gas component of air - nitrogen nitrogen

Which of the following is not the application of nitrogen?

  1. Refrigerant

  2. Metallurgy

  3. Match sticks

  4. Electric bulbs
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Liquid nitrogen is a cryogenic liquid. Like dry ice, the main use of liquid nitrogen is as a refrigerant. 

 Nitrogen is used to provide an inert atmosphere in metallurgy to prevent oxidation in certain industrial processes.
You can't fill a bulb with air or combustion of hot tungsten wire at high temperature will take place in presence of oxygen. You can't maintain vacuum either or external atmospheric pressure will break the glass. So, you have to fill it with non-reactive gas like nitrogen.

Multiple choice chemistry nitrogen and sulfur nitrogen gas component of air - nitrogen nitrogen

Nitrogen is inert because:

  1. it supports combustion

  2. of low boiling point

  3. of high electronegativity

  4. dissociation energy of its molecule is fairly high

D Correct answer
Explanation

The triple bond is pretty strong. Therefore, it needs a lot of energy to break those bonds and participate in a reaction. So nitrogen is commonly referred to as and used as an inert gas (high abundance & low cost.) Dissociation energy of its molecule is fairly high.

Nitrogen gas is very difficult to identify because of its :

  1. High dissociation energy

  2. Characteristic colour

  3. Unreactive nature

  4. High electronegativity

C Correct answer
Explanation

Nitrogen is commonly referred to as and used as an inert gas (high abundance & low cost.) Due to its inert nature it does not react with other compounds. Hence, Nitrogen gas is very difficult to identify because of its nonreactive nature.

Nitrogen is used for filling the electric bulbs, because it is: 

  1. Lighter than air

  2. Capable of giving more light by the bulb

  3. Not helpful in burning

  4. Not poisonous
