Chemistry 2010 Exam

<p>

not COMPLETELY… when you get acid on your SKIN you use its conjugate salt in water to treat it</p>

<p>@nicksyn- I TOTALLY agree! It tested all the stuff I liked/was good at. :)</p>

<p>I’m just glad that I remembered what propane was, since I NEVER studied naming organic compounds. Overall, test wasn’t all that hard (my teacher’s tests are MUCH harder lmao).</p>

<p>omgg lucky ! i didn’t do so well. there were more lab questions on the mc than usual. i had to skip all of them ! except the unknown liquid one haha.</p>

<p>the test killed me overall. i got raped on the FRQ portion. expecting a 2-3, praying for a 4.</p>

<p>

lol that’s why I always take out my battery and throw it in my backpack during all my AP tests (if I hit the power button on the side it would make the AT&T start-up WHOOSH noise). One of my friends’ cell phones vibrated (loud enough for everyone to hear) and the examiner didn’t even look up lol.</p>

<p>omg me too :frowning:
i reeally hope i can get a 4.</p>

<p>I answered all 75 multiple choice questions and the FRQ was a breeze.
I must say, the Princeton Review for Chemistry was unbelievable.</p>

<p>The MC was hard because of all the decimal mental math. After that was over, it was pretty simple. FRQ I thought I dominated. But I don’t know what I’ll score. On the mock exam I took 2 weeks ago I got a 119…which was a 5 by 22 points. I like drawing Lewis dot structures. FYI.</p>

<p>Hey you guys!
So I also took the exam today and you know I have to say it was much easier than I had expected. Although I did make some unnecessary mistakes on the multiple section, I’m pretty sure my raw score was over 50. For FRQ 1 I probably got somewhere between 1/2-3/4 of the question right. FRQ 2 1/2 and FRQ 3 2/3 and for Part B I got almost everything right! (I checked my answers with 2 other people lol) I’m hoping the curve will remain high and I want a 5 so bad! :confused: </p>

<p>Oh and the first reaction for some reason took me forever to figure it out 0__0
I HAVE NO IDEA WHY!!
Well anyway it was:
H+ + OH- –> H20
:smiley:
And I think the others were:
C3H8 + 5O2 –> 3CO2 + 4H20
H2O2 —> H2 + O2</p>

<p>I hated that question
You know, it should be the dilute buffer but because the solution is unknown you have to rinse it with water :confused: I did not put that…</p>

<p>H202 decomposes into water and O2 i thought?</p>

<p>^ You’re right. :)</p>

<p>Whoops sorry ! I wrote the wrong reaction !
I think you’re right but the only reason I thought og mine was because I remember a reaction like
H2 + O2 –> H2O2</p>

<p>I forgot one of the formulas, and I didn’t put the first in a net ionic equation :frowning: </p>

<p>Will they give me partial credit or does it have to be in that form to receive any points?</p>

<p>Must be in that form.</p>

<p>They will definitely give you partial credit :slight_smile:
Correct reactants/Correct Products/Balanced etc.</p>

<p>Does anybody know when the makeup test for AP Chem is?</p>

<p>“H202 decomposes into water and O2 i thought?”
I put this too because the directions say H2O2 decomposes and produces A gas so H2 AND O2 were not BOTH the answer.</p>

<p>How is the exam scored? I know you have MC correct - .25 x Incorrect, but how are the FRQs graded?</p>
