May 2008 Chemistry

<p>I got impatient, so I decided to make a thread early:)
So who's taking it anyway?</p>

<p>I am :/ Only SAT II I'm taking though, so at least I get to get out of there early.</p>

<p>I feel incredibly unprepared for this. I'm comfortable with AP Chem, I did ok on USNCO, but the lack of real practice tests (ie. only 1 available) makes things tough. I don't know how my scores on Barrons and PR will compare to how I do on the real thing. Hopefully those books are scaling correctly to match the real test...I'd be happy with a score like that.</p>

<p>I am :) I've taken 11 (!!) practice tests, I hope I'm ready</p>

<p>I am, not ready though. probably will endup with like a 740-780</p>

<p>Start discussing the problems as soon as we can. T-9 hours.</p>

<p>Now we have two of these threads?</p>

<p>Mine is better</p>

<p>Howmany TTCE did u get...I got 4</p>

<p>Commense Discussion</p>

<p>i just finished mine</p>

<p>what did you get for the ideal gas equations problems where it asks you for the liters?</p>

<p>err I don't think we should be discussing yet...have places like hawaii even taken the test yet?</p>

<p>anyone think it was a lot harder than some of the practice tests in review books? I'm just about ready to cancel it</p>

<p>me too i though it was really hard
i want to cancel it!!!</p>

<p>i put sublimation i was confused w/ the question above it...
i'm deciding whether i should cancel it or not....</p>

<p>c --> co2 is sublimation. It's dry ice subliming to gas.</p>

<p>wat about the other one that vapors is formed above crystal or something? was that sublimation also?? i was soo confused..</p>

<p>and first 5 qeustions i had no idea :( didn't study that part as much...</p>

<p>c to co2 is oxidation, dry ice is co2, but solid form</p>

<p>did you guys get V2O2?</p>

<p>C(s)-->CO2 was oxidation ... oxid. state of C changes from 0 to +4.</p>

<p>V2O2 anyone?</p>

<p>NaCl in water use distillation? and for the Silver Nitrate one, use Filtration?</p>

<p>Also, for the first true false one, I got TF.... Decreasing volume does NOT speed up the particles right?</p>

<p>What about the one with the incorrect lab procedure? I put heating the test tube in the fume hood with a bunsen burner...=D</p>

<p>Question about the first T/F/CE question - was it T and F? The second part of the question asked about speed of the gas molecules .. if they would increase b/c volume decreased but temp was constant. I thought temp chgs speed of gas molecs.. correct me if I'm wrong</p>
