A few questions:

1. I can’t remember if for the equilibrium equation with gases if it said the pressure was increased or decreased . It asked which equation would yield the most product. What did you guys put for the answer?

2. The partial pressure gas question with which of the following three would affect the partial pressure when two gases are mixed. I put all three (I wasn’t sure if choice III about a possible reaction was true)

3. There was a question in the T/F section about particles from nuclear decay…alpha particles and something else, about how they penetrate or something? What was the answer? I put T, F but I had no idea.

4. That question in Part A with the lab equipment…which one was it for the separating HCl and H2 (I think that’s what it was?). I put the last one of the right, but that was purely a guess.

5. There was a question where they give you the molar mass of a carbohydrate of some sort and they tell you the mass of carbon present and you’re asked to determine the mass of the carbohydrate you have. I think I screwed up the arithmetic…I got 96.

6. Gas X is twice as dense as O2…was it 32x2? I got really confused…

7. Acetic acid vs. water. I put T,T CE but I think it’s just T,T?

Anyway that’s all I can think of. I wouldn’t be surprised if everything I did up there is wrong.
