Question

why is nitrogen gas prepared in the laboratory called chemical nitrogen? plz answer right and exact answer​

Answer 1

Answer:

Nitrogen is an inert gas which constitutes about 78% by volume of the atmosphere. Nitrogen gas is prepared in the laboratory by heating the mixture of ammonium chloride and sodium nitrite in the ratio of 1:1. ... Nitrogen is neither combustible nor a supporter of combustion. Nitrogen gas is used to manufacture explosive.

DETAILED EXPLANATIONS:-)

I think nitrogen prepared in lab is a artificial methods;because it is called chemical nitrogen.

Laboratory Preparation of Nitrogen:

In the lab, nitrogen is prepared by heating a mixture of ammonium chloride and sodium nitrite and a small quantity of water. If ammonium nitrite is heated by itself, it decomposes to produce nitrogen gas. However, this reaction is very fast and may prove to be explosive.
