Why is it difficult to test for nitrogen gas in the lab?
The air on Earth is a mixture of several different gases, however it is primarily Nitrogen (Approx. 78%). Thus, it is difficult to test for the presence of Nitrogen as the result of an experiment because it is already present in abundant supply in the air around you.
What is the amount of nitrogen in ammonium chloride?
about 24.99% nitrogen is present in ammonium chloride........
A sample of air that weighs 1.25 kilogram how many kilogram of nitrogen are present?

How do you distinguish between nitrogen oxide and oxygen using a chemical test?
Use a sample of pyrogallol (C6H6O6) in the sample followed by a combustion reaction. This compound absorbs oxygen present.
Is nitrogen present in chlorobenzene?

What test would you use to distinguish between nitrogen an oxygen?
You can test for oxygen by placing a glowing splint (not lit but not out) into the test tube where you think oxygen is present. If the splint relights, that means that it is oxygen. If this doesn't happen, then in your case it will be nitrogen.

What test would allow you to tell the difference between carbon dioxide and nitrogen why would the burning splint test not work?
You stated that carbon dioxide and nitrogen are present, but you did not mention oxygen. Nothing burns without oxygen . . . If you expose limewater to carbon dioxide, it will get cloudy, but will not if you expose it to nitrogen.
