My cousin asked me this question and I couldn't answer it. Is is something within the bonds that changes whether it catches on fire?

Hydrogen and Oxygen are flammable only if they are as independent elements. Not when either of those are combined with any other element. The other way to look at it is.
When something burns chemically the substance is getting oxidised. So when Hydrogen and Oxygen combine they burn(get oxidised) and form water. So water is actually the by product. Water is similar to ash which you get after burning coal.

Oxygen In And Of Itself Is Non Combustible But Is Needed By All Combustible Gasses And Materials To Burn. If You Starve A Fire Of Oxygen It Can Not Continue To Burn.

First of all, Oxygen is not flammable. It is needed for flammable to combust. Water is the product of Hydrogen combining with oxygen when it is burned.

Separatly, yes both are very flammable. Burning them produces water. The H molecules bond with O molecules and release energy as fire. To break the bonds would consume energy. This is the principle that home-made ice cream makers use that make the ice cream freeze.

water is a compound formed by reactionbetween hydrogen and oxygen and according to the basic definition of compound ,it can have properties entirely different from those of its constituents.
so, hydrogen is flammable and oxygen supports combustion but water does not do either of the two.

In kindergarten speak, hydrogen and oxygen in a gasious state are flammable. However when the are bonded in a liquid form to make water, they are not.

in H2O the oxidation states of both Hydrogen and Oxygen atoms are satisfied hence further oxidation of water molecule is not possible.

look here hydrogen and oxygen in there atomic state they r gases and hyrogen is highly immflamable and oxygen is supporting the fire.
but the molecule h2o ie water is in liquid state and it is neutral and cant influence the fire

Water is burnt hydrogen. Think of it - can you burn something that's already totally burnt? When you burn carbon, you create carbon dioxide. You can't burn carbon dioxide again.
