Haha, you came here for academic chemistry help...lol
Chemistry was not my major, but I took college chemistry I&II in my high school senior year...a loooong time ago. But I know something about math and equation solving which is all I need here to solve the second problem (that's all the time I can help with because heck I have work to do here!). The answer is -285.3. Here's the list of equation adding and canceling for it:
CS2 + 3O2 --> CO2 + 2SO2 (-1077)
2S + Cl2 --> S2Cl2 (-60.2)
C + 2Cl2 --> CCl4 (-135.4)
2SO2 --> 2S + 2O2 (+593.8)
CO2 --> C + O2 (+393.5)
Make sense and no question, right? Great. Good luck on the first problem.
