May 2013 SAT II Chemistry

<p>I’m hoping for a 750+. Also have my AS chem structured question exam next Wednesday. For all of you in AP chem, thank academic Jesus that you are not in AS/A level chemistry</p>

<p>im pretty sure the pressure of mercury one was 780 because of this practice problem i did from the collegeboard website.
<a href=“The SAT – SAT Suite | College Board”>The SAT – SAT Suite | College Board;

<p>scroll to the chemistry section, its number 13</p>

<p>Its 720, if it was 780, the gas would push into the pool of mercury b/c the atmosphere is exerting 750. In #13, H the gas pushes out more than the atmosphere, not the case on the test.</p>

<p>@pkvader: That’s a manometer, though, not a eudiometer. The air inside the bulb is exerting that extra pressure on the mercury inside the tube; however, in a eudiometer, if the mercury is higher in the tube, then the atmospheric pressure is greater than the internal gas’s pressure.</p>

<p>did anyone get the answer “all chemical reactions cease” for the equilibrium question?? (It was an except question)</p>

<p>@pkvader yeah, the reactions still continue at equilibrium, just at equal rates.</p>

<p>goddamn omitted six and missed a bunch. what do you think my score can be if i missed like six and omitted six… </p>

<p>i was so pressed for time; i should have done an actual practice test of 90 questions. took ap practice exams but those only have 75 q’s</p>

<p>what was the question about the halogens and how they’re diatomic molecules?</p>

<p>what exactly is the average curve</p>

<p>Ah sweeet. If it’s 720 i got it. I learned all the lab stuff and what a eudiometer was this morning</p>

<p>The curve on the 2005 test in the blue book was -3 raw for 800, then -4/-5 for 790, -6/-7 for 780. I’m hoping the curve on this one will be more generous (maybe -5 raw for 800? fingers crossed) since the blue book test was way easier.</p>

<p>actually, the answer was alpha, gamma, betta.</p>

<p>No; the alpha particles would bend towards the negative side and the beta particles would bend towards the positive side of the capacitor. They go past it but it changes their course. The question essentially tested students on whether they knew what charge was or not.</p>

<p>what was the answer to which of the following has example of both ionic and covalent bonds?</p>

<p>@football1 it was NH4Br</p>

<p>In the first couple of questions (these were the classification ones) did anybody use a choice twice for two questions?</p>

<p>Sorry for being so vague XP</p>

<p>for the first few answers did u guys get like all a and e</p>

<p>chemmy i remember e, a, then e for the first three that’s why i asked lol</p>

<p>yeah then i got that Lol XD</p>

<p>did anyone else get something like that?</p>
