Calculate the value of the standard enthalpy change for each of the following reactions (standard enthalpy for Na2SO4(s) is -1375.653 kj/mole):
a)4HBr(g) + O2(g) = 2H2O(I) + 2Br(I)
b)2Na(OH)(s) + SO3(g) = Na2SO4(s) + H2O(g)
c)CH4(g) + 4CI2(g) = CCI4(I) + 4HCI(g)
d)Fe2O3(s) + 6HCI(g) = 2FeCI3(s) + 2H2O(g)

    See your earlier post. I'll explain something here if you don't understand it but I'm not about to rework four problems just for the fun of it.
