###### Problem Details

Use a standard enthalpies of formation table to determine the change in enthalpy for each of these reactions.

i) CH4(g) + 2 O2(g) → CO2(g) + 2 H2O(l)

ii) 2 H2S(g) + 3 O2(g) → 2 H2O(l) + 2 SO2(g)

iii) 2 NO(g) + O2(g) → 2 NO2(g) What scientific concept do you need to know in order to solve this problem?
