Cumbustion Reaction...?

Question

The combustion reaction of Methane is:

CH4 + 2O2 ---> CO2 + 2H2O

Who can fully explain this to me...

Answer 1

It's a free radical chain reaction.  The unpaired electron on the oxygen molecule pulls off a hydrogen, whch forms a radical that reacts again.  Each step forms another radical and the reaction continues until there are no more radicals left, resulting in the formation of CO2, H2O, CO, and C (in air).  The only time the reaction forms nothing but CO2 and H2O is at high oxygen concentration.

Answer 2

When any hydro carbon under goes complete combustion, it reduces to co2& H2O

Answer 3

Methane and Oxygen react to form Carbon Dioxide and water
