The October CHEMISTRY SATII Discussion

<p>wait then if i skipped 9 questions and got maybe like 3 wrong would i be able to get a 760?</p>

<p>Isn't the curve based on how people scored on the previous test, anyway? I'm hoping for at least 3 or 4 wrong -> 800 so that I have some breathing room.</p>

<p>A raw score of 72 would put you at 750 going by CB's book, and since most people think the curve will be more lenient than that, probably.</p>

<p>I'm pretty sure the curve changes from year to year...and wow, what an incredible first post I've made!</p>

<p>The test in the CB book was in 2002, so its curve probably isn't all that reliable for 2006.</p>

<p>was there a question that asked "how many atoms are in one molecule of <strong><em>" or was it "one mole of one molecule of _</em></strong>"?</p>

<p>hence was the answer 45 or like ___ x 10^25</p>

<p>It was 45.</p>

<p>Was the question involving an aqueous solution of CaCO3 a trick question?</p>

<p>Was I supposed to skip it? because i just pretended that CaCO3 was actually soluble (though my test book has "*** its insoluble" written in it)</p>

<p>Do you remember more about that question?</p>

<p>xyzzy, i'm referring to the 2006 CB book and the curve in it was 82-85 is an 800 and after that 2 raw scores have the same converted score</p>

<p>schmivy, what was the Q involving an aqeuous solution of calcium carbonate?</p>

<p>neutralnuke - I know, I am too. If you flip to the page before the scaled score conversion table, you'll see a footnote saying "...5,571 students who took the original form of this test in November 2002..."</p>

<p>So while the book was written in 2006, their table is for a test in 2002.</p>

<p>ahh, thnx for the clarification</p>

<p>I dont' remember really, but I remember thinking the question was total crap. I tink it involved finding the concentration of one of the elements or something. I took the chem one first, so my memory of it has mostly been squashed under my memory of the math one which I took second (I wanted to get the harder one done first)</p>

<p>Hmm. I don't remember a question like that; the only problem somewhat similar to that that I can recall was the one asking for the concentration of chloride ions...</p>

<p>The only CaCO3 I do remember seeing was the one in the decomposition question. Ah well.</p>

<p>yep remember getting that one wrong - marked F2O3</p>

<p>Fe2O3 was wrong? damn</p>

<p>it's bad when I think that the AP exam was easier than the SAT II (then again I haven't taken any chem since the end of may)</p>

<p>How many questions were on the test - sorry, I couldn't remember. Was it 85 or 90?</p>

<p>85 questions.</p>

<p>I'm trying to make a list of all the TTCE questions.</p>

<p>TTCE - water dissolves salts because of something about the interactions...
TTCE - a saturated salt solution can become unsaturated when heat is added because the solubility of many salts increases with temperature
TTCE - the reaction of Mg and O2 to form MgO
T/F - gamma particles are more penetrating than alpha particles because they have more mass
T/F - potassium is easily oxidized because it readily gains electrons
T/F - atomic radius decreases as you go right across a period because of something about neutrons
F/T - something about helium and argon, second part was that a mole has 6.022 * 10^23 molecules
F/F - NH3 diffuses more slowly than CO2 because a molecule of NH3 is heavier than one of CO2</p>

<p>That's 8. Anyone remember any others?</p>

<p>schmivy - i think it was wrong....
I'm just taking AP chem this year - didn't know much :(</p>

<p>another TTCE Q was about gases absorbing energy when becoming liquids...</p>

<p>Oh yeah, that was F/F because the other part was about covalent bonds being broken during a phase change.</p>
