Homework Help: Chemistry

Posted by Eddie on Tuesday, January 22, 2013 at 6:40pm.

Given the following data:

S(s) + 3/2 O2(g)-->SO3(g) ∆H = -395.2 kJ

2SO2(g) + O2(g) -->2SO3(g)∆H = -198.2 kJ

Calculate ∆H for the reaction

S(s) + O2(g) --> SO2(g)

Could someone please tell me how you would go about doing this type of problem?
