What is the relationship between enthalpies p, q, r and s?

S(s) + H2(g) -> H2S(g) AH=p

H2(g) + O2(g) -> H2O(1) AH=q

S(s) + O2(g) -> SO2(g) AH=r

H2S(g) + 1%O2(g) -> H2O(1) + SO2(g) AH=s

nacl is added to the aqueous of what? ? in order to get a proper answer you have to specify the exact composition of the aqueous solution.

the earth would become to overheated and everything alive on it will eventually die from overheating. plants will eventually die as well, water will evaporate, and it will be nothing but a hot planet without anything living on it.
