If hydrogen were used as a fuel, it could be burned according to the reaction:
H2(g) + 1/2O2(g) → H2O(g)
Use average bond energies to calculate ΔHrxn for this reaction and also for the combustion of methane (CH4). Which fuel yields more energy per mole? Per gram?
H 2 (g) + ½ O 2 (g) --->H 2 O (g) The structural formula for H 2 is H-H and there is 1 H-H bond in 1 mole of H 2 The... View the full answer
