| wow, I actually did better than I thought, lol, I actually got some of these answers.
Oh, I did number 8, it was pretty straightforward, I don't remember the order of the questions or my answers though. | |

| I'd guess, but my school has a pretty bad AP Chem teacher, so we actually never did a practice test :-/ | |

| tm2000s answers are all correct. If you don't have what he has written, then your answers are incorrect. Thankfully, I have all of his answers except formal charge (used electron PAIRS instead of single electrons around central atom!!! damnit!!!) and the shape/diagram of SF4 | |

| Hey guys a question about the wooden splint. If its pure H2 wouldn't that put out the flame? I thought Hydrogen only made a crack sound when other gases were present, but H was dominant.
The units for the rate law were M^-1 * s^-1 right?

| I got C3H7O2 as the empirical formula. And for Question 8, since NaI was in a water solution, the water reacted instead of Na+ and I-, right? | |

| H2 would pop (I also put that the H2 gas would ignite and flame because that's what happened when we did a lab on that way early in the year)
btw, my friend had the emperical formula as C6H7O2 | |
