What is the flammability of nitrogen?

Answer 1

Nitrogen is not combustible.

The National Fire Protection Association has assigned a flammability rating of 0 (minimal fire hazard) to nitrogen.

However, In contact with ozone, nitrogen can oxidize explosively.

Answer 2

If by nitro you are reffering to any of a number of oxides of nitrogen, then the answer is no.

However, the nitro- prefix is often used to describe compounds containing the -NO2 group.

Substances containing this group do tend to be explosive or flammable.

Examples include nitroglycerin, TNT (trinitrotoluene), and nitrocellulose.

Answer 3

Nitrogen itself is not flammable because it is an inert gas, meaning it does not react readily with other substances at normal temperatures. It can, however, act as a diluent in a flammable atmosphere, reducing the oxygen concentration and potentially lowering the risk of a fire.

Answer 4

No. Nitrogen is not very reactive. This is very good for us. Earth's atmosphere is mostly nitrogen. If nitrogen were flammable, oxygen would not be able to exist in the amounts we need.
