Calculate delta Ho for the rxn: Na2O (s) + SO3 (g) --> Na2SO4 (g) given the ff information: 1. Na (s) + H2O (l) --> NaOH (s) + 1/2 H2 (g) delta Ho = -146 kJ 2. Na2SO4 (s) + H2O --> 2NaOH (s) + SO3 (g) delta Ho = +418 kJ 3. 2Na2O (s) + 2H2 (g) --> 4Na (s) + 2H2O (l) delta Ho = +259 kJ The answer should be -581 kJ. I am very confused. thank you.
