the thermochemical equation for th edissocation of hydrogen gas into atoms may be written :

h2-> 2H delta H 1824.2

what is the ration of the energy yield on combustion of hydrogen atoms to steam to yield ion combustion of an equal mass of hydrogen molecules to steam given

2H2(g) = O2 (g) -> 2h20 (g) delta H = -2023.7 kj
