Arguably, the bond energy shown in kcal should be shown in J or a derivative, since J is SI and kcal is not.

Dissociation energy too low?
If the dissociation energy is as low as 3.4 kJ/mol, what acounts for the high heat of vaporization of 40 kJ/mol? Dan Gluck 17:29, 19 June 2007 (UTC)
Because water is actually much more complex. There are monomers, dimers, trimers, teramers, ion-pairs etc. these all add up. Some break when transitioning to the gas phase, some don't there is no simple answerPedroDaGr8 (talk) 02:40, 29 October 2008 (UTC)
