Why are nitrogen oxides produced when fuels burn in vehicles?
Vehicles also need air to burn the fuels they use. Air is about 79% nitrogen. The nitrogen will combust to form nitrogen oxides: N2(g) + 2O2(g) ---> 2NO2 ...
Is it possible to prove that fire needs oxygen and not nitrogen?
Yes. In a lab, light two pieces of wood on fire. Close one in a chamber that is fed pure oxygen and another in a chamber that is fed pure nitrogen. The fire that is fed pure oxygen will burn hotter and brighter. The one that is fed nitrogen will go out. ...

Can fire be produced without air?
Fire can be produced without "air" as air is a mixture of oxygen, carbon dioxide and mostly nitrogen. Fire needs only Oxygen to burn, so if you remove this is will extinguish itself. Without "air" it can still burn as long as it is provided with oxygen. ...
Asked in Chemistry, Nitrogen
How will a fire not burn without nitrogen in the air?
This is not true. It is oxygen in the air which is needed. Burning is a chemical reaction in which the fuel reacts with oxygen. ...
