Because oxygen is required for something to burn. The air mixture adds the oxygen to the gas and allows burning to take place.
The chemical equation for complete burning of octane is: 2 C8H18 + 25 O2 -> 16 CO2 + 18 H2O. This equation shows that 25 moles of diatomic oxygen are required to completely burn each two moles of octane. The gram molecular mass of octane is 114.23 and the gram molecular mass of diatomic oxygen is 2(15.9994). Therefore, the ratio of the mass of oxygen required to completely burn any given mass of octane to the mass of the octane to be burned is 50(15.9994)/2(114.23) or 3.5016, to the justified number of significant digits (the same as the number of digits in the least precisely specified datum 114.23, and the mass of oxygen required to burn 19.8 g of octane is (3.5016)(19.8) or 69.3 grams to the justified number of significant digits, now limited by the less precisely specified datum 119.8.
Iron will burn in pure oxygen.

The balanced equation for the reaction is 2 C4H10 + 13 O2 -> 8 CO2 + 10 H2O. This shows that 13 moles of diatomic oxygen are required to burn 2 moles of butane. By proportionality, (4.8/2)13 or 31.2 moles of oxygen are required to burn 4.8 moles of butane. This corresponds to 31.2(32) or 1.0 X 103 grams of oxygen.
C3H8 + 5O2 -> 3CO2 + 4H2O That is the complete combustion for Propane.

U turn off the oxeygen so it dosnet burn you
Anything which burns requires O2, so oxygen is required for fuel to burn. Also this is known as a combustion reaction and an exothermic reaction.
No
Yes.
oxygen must be present in order for fuel to burn.
Oxygen itself isn't flammable but it is required for something to burn
Burning is the rapid Oxidation of a Compound. Therefore the Element Oxygen is required.
