<h3>What is the oxidation number of oxygen in H2O?</h3>

Oxygen almost always has an oxidation number of -2, except in peroxides (H 2 O 2) where it is -1 and in compounds with fluorine (OF 2) where it is +2. Hydrogen has an oxidation number of +1 when combined with non-metals, but it has an oxidation number of -1 when combined with metals.

Formula for ΔE:

$\Delta E = \sum \text{Bond energy of recatants}- \sum \text{Bond energy of Products}$

$= 6 ( B.E_{C-C}) +12 (B.E_{C-H}) +(B.E_{o \ = \ o}) - 6(B.E_{C-C})-10(B.E_{C-H}) -( B.E_{C=0}) -2(B.E_{0-H})\\\\ = \bold{2 (B.E_{C-H}) +(B.E_{o \ = \ o}) -( B.E_{C=0}) -2(B.E_{0-H})}\\\\$
