Question

If pure hydrogen and pure oxygen are both very flammable, why is water not?

Answer 1

Because Hydrogen and Oxygen LOVE hooking up. So when you have the two of them separated, just a little spark they will combine and release a bunch of energy – sometimes explosively.

But once they are together, they’re really hard to pull apart or to get to react with other things, exactly because they LOVE being together so much.
