Bond Energies and Enthalpy of the Reaction takes energy to break a bond, bond energies are always positive. Conversely, energy is released when bonds are formed. Thus, the enthalpy change for a reaction can be approximated from \( \Delta H_{\mathrm{rxn}}=\sum(\Delta H \) breaking \( )+\sum(\Delta H \) forming \( ) \) where \( H \) represents bond energies for the breaking (positive bond energy) or forming (negative bond energy) of a bond and \( H_{\mathrm{rm}} \) represents the overall enthalpy for the reaction. Use the table to answer questions about bond energies. Gaiculate the bond energy per mole for treaking all the boncis in methane, CH. Express your answer to four significant figures and include the appropriate units. Part B Calculase the bond energy pes mole for breating all the bonds of caygen, \( \mathrm{O}_{2} \) ? Express your answer to three significant figures and include the appropriate units. Part c Calculate the bond enertyy per mole for lonining al the bonds of asafor molecules. \( \mathrm{H}_{2} \mathrm{O} \). Express your answer to three significent figures and include the appropriate units. Part D Caiculaie the bond energy per mole for forming al tee boods of carbon diokid, \( \mathrm{CO}_{2} \). Express your answer to four significant figures and include the appropriate unite.
