> but the oxygen bonds we're breaking Err it says the exact opposite: > The double bond in O2 is much weaker than other double bonds or pairs of single bonds, and therefore the formation of the stronger bonds in CO2 and H2O results in the release of energy Weaker bond = less energy needed to break it.
