This is driving me insane:----

What is the difference between a combustible substance and supporter of combustion?

Thanx in advance...

Start by looking up the definitions (e.g. on google).

This is the answer I get:

a gas, as oxygen, the combination of which with a combustible, as coal, constitutes combustion.

So, between H₂ and O₂, which one would be a combustible substance and which one would be the supporter of combustion?

Thanx...

Combustion is the reaction of a fuel (combustible substance) with an oxidant (supporter of combustion). It is a redox reaction in which the fuel is oxidised in a highly exothermic reaction (that usually produces a flame).

Write a chemical equation for the reaction. The species that is oxidised is the fuel, the species that is reduced is the oxidant.

Thanx a lot.....You are awesome...!

None of my teachers could explain this to me. You will not find an answer better than this anywhere..

thanx once again...
