Thermodynamics of methane combustion

The balanced equation is CH4(g) + 2O2(g) ---> 2H2O(g) + CO2 (g)

Given the equation: delta G = delta H - T(delta S) 

Since the values of both G and H are so similar, the only plausible conclusion would be that the reactants and products are roughly the same. Therefore, delta S must be a number very close to zero so that any increase/decrease in temperature won't affect the

Practice MCQ Exam

1. The problems I struggled with were more or less those that I didn't remember how to do. I saw these questions and remembered learning about them but I couldn't connect the pieces and remember back to the time we learned about them.
2. I really understood the recent problems that we've been doing in class recently since they were fresh in my mind. These problems seemed a bit easy and didn't provide much trouble. I also remembered doing some of the problems before and I remembered the way I did them.
3. 13. C.I remember getting this problem wrong on a quiz and once again, I got it incorrect again. I think memorizing differences between different types of bonding would help.
19. B. I thought that C-F bonds would break easier since they weren't equal whereas the C-H bonds were.
24. A. OH- is the only conjugate base and is therefore the answer; the conjugate base of acid 1 is <7.
29. B. Misread Periodic Table.
