Hi,
as I know, nitrojen is, at low temperature, exit from a reaction as entered to it? So for ex. in a combustion reaction, it doesn't burn? And at high temperature, it combine oxygen to form NOx, but isn't it an combustion, is it?

Briefly;

x + O2 -> .

Every oxygen reaction doesn't mean combustion, does it?

Thank you and have a nice day...
