Is the hydrogen in H2O the same as the very flamable gas?

In fact, the reason that elemental hydrogen (H2 molecules in a gas under normal conditions) is VERY flammable is that it reacts explosively with oxygen to produce water. In fact, the name hydrogen comes from Grrek words meaning water-forming.

Water contains hydrogen and oxygen. Why doesn't it burn?
Water doesn't burn because it's already burnt.
Oh, sure, it doesn't look burnt. Nonetheless, it's one of the chief products of combustion. Light a candle, gas jet, whatever, and what do you get? Mainly carbon dioxide and water. We started off with a hydrocarbon and the hydrogen oxidized. The result is water, a substance far more stable and thus less flammable than an unburnt mixture of hydrogen and oxygen.
Still, if you try hard enough you can get even water to burn. Try torching the stuff in the presence of fluorine gas. You get a nice hot flame that produces oxygen and hydrogen fluoride, which are more stable than water plus fluorine.
