OFFICIAL Oct. 8, 2005 SAT II: Chemistry Forum

<p>I dunno I might just cancel my scores and forget about chemistry forever because obviously I'm not very good at it.</p>

<p>man, i was getting like 750 on practice tests, and the one in collegeboard i like almost aced??</p>

<p>for the diagram of the Bohr model for jumping electrons, did u guys get A, E, and A?</p>

<p>I had no idea for that question, had never seen anything like it before. I think I put like C, B, and maybe I omitted the third one.</p>

<p>Did anyone get those questions where they wanted you to balance find the coefficient for something when they only gave you the first half of the reaction?</p>

<p>NACL was not TT CE
it was TF</p>

<p>NACL causes the vapor pressure to be lower NOT HIGHER because the Na+ and Cl- particles impede the water from pushing up. BECAUSE the vapor pressure is lower the boiling is slower/takes a higher temperature</p>

<p>so what do you guys think you will get? I think below :(. Im cancelling and retaking in nov</p>

<p>how many "CE" answers did u guys get? I got 4.</p>

<p>That chemistry exam was absolutely ridiculous. I don't understand how any SAT II exam can be that hard!!!!</p>

<p>My D commented that the test was far more difficult than the practice test was and that, for the first time in in any standardized test, she didn't finish...had to leave 4 questions blank. The curve is quite generous, however.</p>

<p>has it ever been this hard??</p>

<p>the curve better be the best ever....seriously. i think we all agree this was one of the hardest chem SAT II tests we've taken. </p>

<p>ramsfan: I got lucky on that question, because we just studied the exact diagram in my chem class on friday. the answer for the ionization potential for H was the line starting at the ground state going all the way up to the 4th energy level (since an e- has to get knocked off to ionize, it has to get excited enough to jump past the energy lvls, so it goes all the way) i hope that was understandable =&lt;/p>

<p>for the bhor model i got C as one answer, that one was where the line was the longest</p>

<p>I also got 4 T/T/CE. I remember that I got both 101 and 102 were T/T/CE. I think the other two were 108 and 112, but don't ask me to remember what the questions were.</p>

<p>the bohr model set of three, i put E for the middle one (lowest energy) and omitted the other two.</p>

<p>btw, i heard somewhere that the curve is pre-determined? is this true?</p>

<p>SalikSyed, you're rite about the NaCl one. I think I remember that I did put T/F, or at least I hope that's what I did. Adding an ionic compound to a solute always raises the boiling point, lowers the freezing point, and lowers the vapor pressure.</p>

<p>the test difficulty .. was some what like the barron tests for me.. wasnt easy tho. I skiped about 4 questions and circled aLOT
when the examiner said 5 mins left I had like 10 questions to go -.-''</p>

<p>Bump
Bump
Bump</p>

<p>That test was SO hard. I skipped about 15 and God knows how many I missed! I can't cancel though - this is my re-take. :(</p>

<p>grays what do you mean you cannot cancel? You can cancel only once?
I've found this test not so hard for me but I did too slowly, I am so tense and check the questions I did over and over again because I am afraid to did it wrong. and until 5 mins left I just reached question #50. then I rushed 10 question in 5 mins and left 10 blanks. damn, I think I should try practise my speed and re take it Nov. I am not sure whether to cancel my score or not. can Some one give me a little advise?</p>
