<p>Hey guys, it's less than a day away from SAT chem....... hopefully we all do well... </p>
<p>We can discuss answers to the test tomorrow. </p>
<p>If anyone is still up, I’m curious as to how well each of you studied.</p>
<p>I really only studied in these last few days, but I finished the Barron’s book one time through and scored in the high 700’s (770-800) on two of the practice tests according to Barron’s very lenient scale. I took a Princeton Review practice test and easily got an 800 on that. </p>
<p>I’m just hoping for no curveballs and a minimization of weird and relatively novel information like… household chemical products. ._."</p>
<p>time to slep zzz</p>
<p>What’d you get for the cadmium percent composition question? Cd(OH)2</p>
<p>What was the answer for the question about the sudden decrease in PV? Also, I can’t remember if the one question in part A for the graphs said reactants or products? </p>
<p>What do you predict the curve for this test will be</p>
<p>PV was condensation. The gas liquefied, so the pressure and volume each decreased. The graph question said products.</p>
<p>What did you guys think about the test? What do you think were the hard questions? </p>
<p>I thought a few questions were difficult to do without calculator, such as the percent composition one with Cd O and H</p>
<p>The Cadmium one was A. 100%</p>
<p>Also, the CxOy question. I got C2O3.</p>
<p>What did you guys get for the Modern Atomic Theory one? </p>
<p>I got C2O4, because you have to take account of the H2O formed as well.</p>
<p>wingtour2000 no you don’t because its not a hydrocarbon. The compound was just made up of C and O. Where would the H have come from?</p>
<p>oh ■■■■ ur right man lol. tnx for the insight. </p>
<p>I got C2O3 as well</p>
<p>Modern Atomic Theory question asked which of the following was false, and the false choice was the one about atoms being indestructible.</p>
<p>It wasn’t too hard, but I ran out of time and left 7 blank. What do you think curve will be like?</p>
<p>@wingtour2000 not it wasn’t A lol. I had 10 minutes left and I spent 5 minutes on the question going through each answer. I forgot the letter though . 77% Cr, 21% O 1.4% H so Cd(Oh)2</p>
<p>The false choice for atomic theory is multiple nuclei. I thought. Online it says "With the discovery of subatomic particles after Dalton’s time, it became apparent that atoms could be broken into smaller parts. The discovery of nuclear processes showed that it was even possible to transform atoms from one element into atoms of another. But we don’t consider processes that affect the nucleus to be chemical processes. The postulate is still useful in explaining the law of conservation of mass in chemistry. A slightly more restrictive wording is “Atoms cannot be created, destroyed, or transformed into other atoms in a chemical change”.</p>
<p>and c2O3 definitely </p>
<p>For anyone that remembers it was like questions 6 and 7 is ammonium nitrate a white solid and copper sulfate hydrate a blue solid?</p>
