It's supposed to be zinc oxide going in, so it probably looks more like this:

ZnO + energy → Zn + O Zn + 2 H2O → Zn(OH)2 + H2

(I know that's not balanced, but yours isn't either)

Maybe you can then get the zinc hydroxide back into oxide without too much trouble. It disassociates in water, leaving you with hydroxide and zinc ions.

Correction, there needs to be a newline there.

ZnO + energy → Zn + O

Zn + 2 H2O → Zn(OH)2 + H2
