How can you recognize oxidation reduction reactions?
By a change in formal oxidation number of the participating reactants with respect to the products.
See this old answer for some tips and principles. Any reaction that involves a change in formal oxidation number is a redox reaction. Under this umbrella lies simple combustion reactions of hydrocarbons, e.g.:
We have balanced this directly with no pfaffing about with electron transfer. But we could assign oxidation numbers to the individual atoms, and use the method of half equations:
And we add
To give the original equation as required.
