What kind of things do you get partial credit for?
[/QUOTE]
</p>
<p>If you mess up something you can only get penalized for it once. That means that if you make an improper calculation than a correct one you only lose one point. On some two parts questions just that setup gets you points. On the lab question, getting the first or second hald of the procedure could be partial credit. In general, however, there isn't much partial credit on this exam because there are so many 1 point questions.</p>
<p>i thought it was okay.
the last problem on the free response threw me off.
my chem class focuses more on calculations, so i wasn't expecting that.</p>
<p>i agree with most of you.
mc was not bad.
free response sucked. i stared at the first reaction since we learned nothing of that sort. same with the eq problem. we mentioned it briefly but never did an example of it. aggggh, i also forgot how to do the lab questions because i did it in chem1 :(</p>
<p>I practiced soooo much Kc and Keq and tons of acid base/buffers. I didn't even think about anything else. The first question really kind threw me for a loop. I thikn i got the first part......but the second half was confusing...
damn....</p>
<p>Although I'm not going to say it was easy, it was, however, easier than the practice tests that I took before the test. Both the multiple choice and the FRQ were easier than I expected except I hate conceptual questions.</p>
<p>the multiple choice wasnt bad, left like5 blank and guess on a few, only problem was with the calculations >_< i needed a calculator. </p>
<p>The second part i thought was quite easy, my teacher told us the day before they were due for a gas equilibrium question and they really didnt make it that hard. The rest was good must easier than practice tests i was taking with like a million calculations, we had actually done the lab w/the hydrated compound in class. The reactions were a mess, but they only count for 10% so i bs'ed most of them. Overall i predict a 4 :)</p>
<p>ok. so i agree that the MC was pretty easy, but the Free response..hmm. it is definitely just me, but for some reason, i didn't really get how to do the first problem (gas equilibrium). but i understood and got like 90% on the other 5 questions. If i got like 60 raw on the MC, can i get a 5????</p>
<p>The MC was pretty easy relatively-I found the 1999 and 2002 exams much harder and more in depth. I'm guessing I missed 10 minimum and 20 maximum.</p>
<p>The free response questions were relatively easy too-especially the non-calculator section. The calculator section wasn't anything out of the ordinary but for some reason I ran out of time and left half of question two blank. =/</p>
<p>I'm predicting a four but hopeful for a five. The test was much better than I expected it to be.</p>
<p>haha if you want to discuss mc questions, don't do it here.
we spent like two days on complex ions, during which i learned absolutely nothing, but i managed to cram it in the day before. basically it's a transition metal (or Al) with ligands (polar molecules & anions ex. NH3, CN-) around it, all written in brackets & usually the # of ligands is 2x the charge of the ion.</p>
<p>The complex ion one was actually very simple. I barely knew my complex ions but could do that one no problem. I screwed up on the 2nd or 3rd one though.. with oxygen gas.. Its funny cause I looked it up on google and it appears there was a yahoo answers page made for it, but the URL doesn't work and its still on the google search results (2nd one). I think CB took it down since they used it on the test... IDK</p>
<p>The potassium oxide one was very easy as well.</p>
<p>I don't want to say the exact answer for the complex ion one, but the Na ion cancelled out as a spectator ion, and it was left showing that the hydroxide ion combined with the aluminum hydroxide to create a complex anion, with aluminum and hydroxide involved.</p>
<p>i put 4 for the complex ion one too, but now i'm pretty sure it's 6? i mean i know my answer EXISTS, but it might not be what they were looking for? :|</p>
<p>As far as I know, as long as your answer is a valid possibility, it's considered correct. On a practice one I did, it didn't matter how many ligands you included, as long as you balanced the equation properly.</p>
