Water is the waste product of the combustion you are describing. It has already been burned.

Uh, yeah. That pretty much covers it.

Water is the "ash" left over from burning hydrogen.

Varsha: Please look up the definition of a "compound" in your chemistry text.

To others: Something being a combustion product does not mean the thing is immune to further combustion (eg: CO, aldehydes), and that's besides the point here. Furthermore, water is most certainly nothing like an ash. An ash is the uncombusted residue; water is a combustion product.
