Question

If hydrogen were used as a fuel, it could be burned according to the following reaction: H2(g) + 1/2O2(g) --> H2O(g) Use average bond energies to calculate delta H rxn for this reaction and also for the combustion of methane (CH4). which fuel yields more energy per mole? per gram?

Answer 1

The fuel that yields more energy per mole would be Methane while the fuel that yields more energy per gram would be hydrogen. I am hoping that this answer has satisfied your query about and it will be able to help you.
