I've been looking everywhere and haven't a clue of what it could be.
A source would be appreciated, thanks.

I do not have a reference, but can tell you that Ethanote (Acetate) ion has the negative charge delocalised over 2 oxygen atoms. This means that the bond energy is between that of a carbon-oxygen single bond and that of a carbon-oxygen double bond.
The bond energy for the carbon-oxygen (double) bond in CO2 is 799 kJ/mol while a single bond C-O is about 358 kJ/mol, so the answer is between these. It is probably in the ball park of 580 kJ/mol.
The true or more accurate answer is a very complexed Physical Chemistry calculation.

No, the oxygen of the ethanol attacks the carbon of the carboyxlic acid (ethanoic acid, a.k.a. acetic acid). The -OH group that was bonded to the C=O group is expelled. It is called a Fischer esterification mechanism. The other mechanism being described in another answer is not realistic because it means the formation of a primary carbocation, which is not supported by experimental evidence.
