H2O has 2 O-H bond
So,
1 mol of H2O has 2 mol of O-H bond
So,
Energy required = 2*BDE(O-H)
= 2*460 KJ
= 920 KJ
Answer: 920. KJ

Calculate the bond energy per mole for breaking all the bonds in methane, CH4
Part ACalculate the bond energy per mole for breaking all the bonds in methane, CH4.Express your answer to four significant figures and include the appropriate units.ΔHCH4 =1656 kJmolCorrectIn CH4, the energy required to break one C−H bond is 414 kJ/mol. Since there are four C−H bonds in CH4, the energy ΔHCH4 for breaking all the bonds is calculated asΔHCH4=4×bond energy of C−H bond=4×414 kJ/mol=1656 kJ/mol CH4 moleculesPart BCalculate the bond energy per mole for breaking all the bonds of oxygen,...
