To calculate the bond energy required to break apart a single molecule of methane CH4 into its individual atoms C and 4H , we need to know the bond energy of a single C-H bond. The average bond energy of a C-H bond is approximately 414 kJ/mol.Since there are four C-H bonds in a methane molecule, we can calculate the total bond energy required to break all four bonds as follows:Total bond energy = Number of C-H bonds x Bond energy of a single C-H bond Total bond energy = 4 x 414 kJ/molTotal bond energy = 1656 kJ/molTherefore, the bond energy required to break apart a single molecule of methane CH4 into its individual atoms C and 4H is approximately 1656 kJ/mol.
