Average Bond Energies (per mole of bonds) H-HC-HC-CC=C0-HC-0 Bond C=0 0-0 0-0 Bond energy (kJ/mol) 432 413 347 614 467 358 799* 495 146 The chemical equation for the combustion of ethanol is as follows: C₂H5OH+30₂ → 2CO₂ + 3H₂O Use the table of average bond energies above to calculate the total energy transferred out to build all these bonds in the products. You may find recreating the table below on scratch paper helpful in calculating the total energy transferred.
