<p>omg I almost ran out of time~~!!</p>
<p>I didn’t spend too much time on any question and tried to pace myself… but still! kinda rushed the last few questions. arggghh~!!</p>
<p>how did you guys do?</p>
<p>I think the difficulty was not too bad… tho some of the questions from the first part was quite difficult…for me.</p>
<p>For me, I finished in 45 mins, so time wasn’t a factor. I did massive overprep ( I think I did ever chem SAT paper in existence) so I was quite prepared. Overall, I did rather well :)</p>
<p>I didn’t do any prep. When I signed up I figured I’d be prepping for the AP anyway, and that the material would overlap. But I haven’t done ANYTHING for AP Chem, so I haven’t done anything for SAT Chem either.</p>
<p>I really, really want an 800, though, and won’t be satisfied with anything below it. I’m not TOTALLY confident, but… I don’t know. There’s no other date I can take it (I don’t want to pay late fees for June) and I’m positive I got 750+, so… yeah.</p>
<p>I finished in about 45-50 minutes.</p>
<p>yeah i was running out of time in the end and i had to rush for alot of the questions at the end :(</p>
<p>Don’t discuss questions until 12 PM.</p>
<p>I don’t we are ever suppose to discuss questions</p>
<p><a href=“define: sieve - Google Search”>define: sieve - Google Search;
<p>It was a little harder than I thought.</p>
<p>hard! char</p>
<p>So was sieve right?</p>
<p>idk…thats what i put</p>
<p>theoneo: what part of Nj are you from?</p>
<p>I don’t think sieve was right.</p>
<p>what was the right answer?
magnet, extraction with water??</p>
<p>i think its sublime, iodide compounds have a tendency for this</p>
<p>The first part was unusually confusing, but the rest was really easy.
When are we allowed to discuss the questions?</p>
<p>i put sublime…it couldnt have been water cuz wouldnt the potassium react?</p>
<p>so basically it’s 2 solids and 1 liquid, right?</p>
<p>hm… I think none of the methods really work with just 1 step…</p>
<p>i said extraction with liquid…cuz the KI would form KOH and HI…and u could then take out the sand and iron…and then evap the water…leaving KI…so yeah it would have to be multistep</p>
<p>K+ doesn’t react with water (at least I don’t think it does). K by itself reacts with water.</p>
<p>smder, that’s what I put too.</p>
<p>did the question say the method should separate all 3 substances individually?</p>
