10. Bond energies like those found in your book can be found by working backwards from reactions in which all but one or two of the given bond energies are already known. For example, the energy change associated with the combustion of formaldehyde is -465 kJ/mol. Given this and the following equation, calculate the energy of the C-O double bond in formaldehyde. Compare this to the listed bond energy for C-O in carbon dioxide and speculate as to why there...
