<p>I can’t remember… I just remember subtracting two numbers because when you subtract that is the amount that isn’t soluble and is therefore the amount left.</p>
<p>Ya, because didn’t the solubility drop from 20g/100ml to 15g/100ml, so that means that 5 grams became came out of the solution and is no longer soluble.</p>
<p>This test sounded pretty hard…</p>
<p>Were there any questions about:
Voltaic/electrolytic cell?
Organic chemistry
Flame test</p>
<p>How much questions were about KSP and solubility?</p>
<p>Thanks in advance! I’m just wondering on what I should focus on.</p>
<p>It is still dissolved. It doesnt come out of the solution.
Assume we remember the following correctly:
At 100 C, 20g can dissolve
At 20 C, 15g can dissolve
If you put 20g in 100 mL of 100 C water, then lower the temperature to 20 C, how much solute will be in the solution?</p>
<p>The answer is 20g. Nothing will come out, it will become supersaturated. That is how something becomes supersaturated.</p>
<p>@mjmsh22 I put 20g too because you don’t need chemistry knowledge to interpret a graph. I think that question was testing your knowledge of supersaturated solutions. </p>

If I remember correctly, there were no questions about voltaic cells. There were however questions about organic chemistry (I think it asked something about ethyne). I don’t recall anything about flame tests.</p>
<p>yeah i remember that organic chem question. Anyone remember the answer to that?</p>
<p>Scores are out! How did everyone do? I was expecting mid-700s, but I got an 800, so I’m pretty happy!</p>
<p>790 10char</p>
<p>780 chem (710 at June) and 800 for math lvl 2
Literally crying right now</p>
<p>800 chem, first try</p>
<p>800 for chemistry, math 2 and physics :D. First try and it worked out well.</p>
<p>I got 770 in SAT CHEM. you guys make me feel bad now :(</p>
<p>I got a 770 also! im excited lol</p>
<p>750, not ecstatic but its decent, considering I left 7 blank becuase I didn’t have time to finish the four balancing problems, and I definitely know of 2 I got wrong. What do you guys think, worth retaking?</p>
