<p>How harsh do you guys think the curve will be? Could it be 4 wrong/5 omit = 800?</p>
<p>wat is the normal curve? i have no idea what to expect >_></p>
<p>The blue book says a raw score of 82-85 is 800 and 61-81 is the 700 to 790 range. My Barron's book says 75-85 is 800, and 55-74 is the 700 to 790 range.</p>
<p>I hope the curve is more like the one in Barron's. x_x</p>
<p>anyone take it b4 who knows wat CB normaly does. i cant take barrons' seriously because the test is so much different than the real thing.</p>
<p>If the curve is less 80, i'm getting an 800 for sure :D</p>
<p>TF question:</p>
<p>crystal salts must be heated multiple times
to find the amount of water in the crystal, all water must be evaporated</p>
<p>TT ce?</p>
<p>Yes. I remember doing this expirement in class. We had to heat our epsom salt 2-3 times to make sure we got all of the water out of it before we could try to calculate how much water was in the epsom salt originally.</p>
<p>yea us too.</p>
<p>uhm for the one where it said molarity of something that was 56 g. the answer was 1.4g???</p>
<p>Yup........</p>
<p>What was the answer to the question asking ....which of the following is not a chemical property?</p>
<p>density. (10 chars)</p>
<p>Okay, uh..was there a TF question that involved _____ because the halogens are gases at STP?</p>
<p>huh? (10 chars)</p>
<p>I mean..."_____ (can't remember first part) because the halogens are all gases at STP."</p>
<p>i dont remember the first part either. second is F tho >_> </p>
<p>FF seems to ring a bell</p>
<p>i think it was if all diatomic molecules are gases at rtp BECAUSE ____ . I put FF (NaCl is a counterexample). I don't think it mentioned halogens though; the trick was to see if you thought only of halogens as possible diatomic molecules.</p>
<p>Sorry for the double post but i think i remembered the question.</p>
<p>It was "Chlorine is a gas at STP BECAUSE all diatomic molecules are gases". The answer was TF. Maybe thats a different question though.</p>
<p>im pretty sure its FF. iodine and bromine are not gases at STP but are diatomic...</p>
<p>I remembered another question today. It was in the true-false section. It was something like "all chlorine atoms have the same mass number," which is false because chlorine has different isotopes.</p>
<p>wat are we callin the curve guys? -4 or -5 for 800?</p>
<p>I think its usually minus -3 for 800 (so 2 wrong max). I hope its minus 4 then we can get 3 wrong. But the first 3 questions were highly disputed so the curve might be lower.</p>
