The combustion of hydrocarbons in oxygen is an example of a fast redox reaction.
CH4 + 2O2 --> CO2 + 2H2O
Methane is the reductant; it is oxidised by (loses electrons to) oxygen. Oxygen is the oxidant; it is reduced by (gains electrons from) methane. More specifically, the carbon atom in methane formally loses all eight of its outer shell electrons to the four oxygen atoms (two per atom). The oxidation state of carbon changes from -4 to +4, while that of oxygen changes from 0 to -2.
After a confrontation with Houdini I rode home in a frenzy and everything came off in a huff before retiring to my trailor for a must needed release of anger frustration and sadness, a fellow campmate captured it here! Oh the trials and tribulations!
