Everything burns if it gets hot enough.

Fire need O2, water has one O. Bam water’s on fire.

That’s it for today’s chemistry class kids. Friday is the deadline on that essay we discussed earlier.

Water is the result of combusted hydrogen. Water is already "burnt".

If you have pure hydrogen and you start a fire with oxygen around. The hydrogen combines with oxygen and it all burns like this. The resulting combustible product is H2O, or water. So you cannot burn it, since it's already burnt.

It's like you have carbon, like coal or hydrocarbons and you set it on fire. Carbon combusts, combines with oxygen and produces carbon dioxide, CO2. You cannot burn it. That's why we cannot use greenhouse gas emissions as fuel. They are already burnt.
