<p>an element is paramagnetic if it has unpaired outer electrons (usually applies only to transition metals) for example Cr is highly paramagnetic because it has 5 unpaired electrons in the 3d orbital… On the other hand, Zn or Cu is highly diamagnetic because all of their outer electrons are paired (10 d e-)</p>
<p>I just tried a Kaplan practice test and ended up getting 690 (ouch!). I’ll probably look over the topics that I ended up missing the most and go to sleep soon…</p>
<p>Hey guys, anyone here take the CD Model Test 1 on the barron’s book. I just took it and got a 800, should I stop studying?</p>
<p>I just got a 490 on the Official. Ouch.</p>
<p>I guess my game plan now is hope I get lucky, and omit as many questions as needed.</p>
<p>Lol maybe ur just stressing too much. And its night time and all so that could be why.</p>
<p>Anyways, </p>
<p>Good luck everyone! Lets pray for a decent curve and straightforward questions…</p>
<p>HOW DID EVERYONE DO? i think it was *<strong><em>ing easy guys. i ended up omitting like 3-4 questions and i wish we could get a calc cause their was one question with PV/T=PV/T which *</em></strong>ing ****ed me off. ended up saving it for last and was half way through the problem when time endedD:</p>
<p>that was pretty easy lol (i think). completely over prepped for it</p>
<p>can we discuss the questions now?</p>
<p>that wasn’t too bad at all. when’s embargo lifted? can we say the # of CE’s we got?</p>
<p>imo i thought it was pretty easy. all the calculations were basically reducable (sp?) to simple fractions</p>
<p>How many CE’s did you guys get?</p>
<p>there were 4 ces</p>
<p>the last one about co2 polar and linear
the one about NaOH dissociated into OH-
and two others</p>
<p>**** are u serious altamash? i am so stupid… seriously thought that co2 wasn’t linear so i did TF ><</p>
<p>Erm… I think I got 6 CEs…</p>
<p>this test was amazingly easy compared to practice tests 
only -1 so far ! 
& yesssssss omg haha 4 TTCE’s whew
i think TTCE’s were hecka easy this test
btw was the K + H2O OH- and H2??
and for the first 4 Qs buret and beaker was the only choice that wasnt used right?</p>
<p>^ correct :)</p>
<p>So…I decided to take this one on the spot b/c my ride was late, haha How’s the curve on chemistry?</p>
<p>My CEs:
Linear CO2
Iron wire rusting
NaOH dissociation
one more that I am forgetting…</p>
<p>I did TF because it said CO2 was a linear polar bond…and it’s not, is it?</p>
<p>^It is. The C-O bond is polar since electronegativity of C isn’t the same as electronegativity of O. The bond’s weakly polar, but still polar.</p>
