Calculating Enthalpy Change
Calculate the Change in Hf for sulfur dioxide, SO2 from its elements sulfur and oxygen. Use the balanced chemical equation and the following information.
S(s) + O2(g) -> SO2(g)
S(s) + 3/2 O2(g) -> SO3 Change in Hf = -395.7 kj/mol
2SO2(g) + O2 -> 2SO3(g) change in Hf = -198.4 kj/mol
A detailed explanation would be super helpful cause for some reason I struggle with this concept and any shortcuts just throw me off >.
