I don't understand your question, water molecules are fully oxidized. Perhaps you meant to say "ten hyrodgen molecules", which would make sense.
Also, Vivek got this wrong:
"10 (H)2O -----> 5(O)2 + 10 H. Also energy will be released"
It should read:
"10H2O -----> 5O2 + 10H2. But energy is required."
The reverse equation :
10H2 + 5O2 ----->10H2O
is the oxidation (burning) of ten hydrogen gas molecules to form ten water molecules. Energy is released by this reaction.

10 (H)2O -----> 5(O)2 + 10 H.
Also energy will be released,
