AP Chemistry Test 2012

<p>Okay, I'm really quite confused. It seems like everyone else who took the AP Chem test at my school on Monday had a different free response test and in addition the College Board just posted the questions online and none of them are the same (they actually seem way easier). What happened to my test then? Where are the questions why did no one else have the same one as me (btw, the one I had included the combustion of propyne in free response 4 instead of the strontium oxide that most people had). What's going on!?</p>

<p>i’m pretty sure there was more than one form of the AP chem test this year, b/c on the official AP chem thread (which got deleted apparently…i think because people were comparing answers) some people said they had different FRQs than the one most people had !</p>

Here is the FRQ. Could someone be so kind as to tell us the correct answers, just to easy my heart to see what I got?
Maybe we could make a compilation of answers/ responses that are correct.
Please and thank you!</p>

<p>Pretty confident in these, if you see any errors, let me know.</p>

<p>I thought the test was just about as hard as the practice one we took. I was confused on question 2 part c- how did you get 1.0atm?</p>

7

<p>@Maybechemist</p>

<p>You see .600 CO2 and .800 H2O?</p>

<p>It’s a ratio; 3 CO2 : 4H2O. You know that it was a combustion reaction.</p>

<p>You know the formula was C3H8 + 5O2 yields 3CO2 and 4H2O.</p>

<p>And basic stoichiometry tells you; .600/3 = .200 atm multiplied by 5 O2 is 1.00 atm.</p>

8

<p>for 5e, if you have 3 unpaired pair of electrons, it wouldn’t be linear…no?</p>

9

<p>@annabanana; it is bent, but it didn’t tell you you needed to do that! haha.</p>

10

<p>@qAnton the question said that I3- was linear…?</p>

11

<p>It is linear due to the bipyramidal e- domain geometry. 2 bonding and 3 nonbonding domains is linear.</p>

12

<p>alrightyy, sorry about the argument. thank you for the help :)</p>

13

<p>@qAnton- thanks- maybe I won’t be a chemist.That was actually pretty obvious</p>

14

<p>I don’t understand what they mean by “equating to quantify the differences in difficulty between versions of an exam”. Will some with a higher understanding of English please comprehend this :)? Is there gonna be separate curves or not?</p>

<p>There better be separate curves because O was way harder than E at least on MC.</p>

15

<p>Yes, different curves. As in, the pass rates for both versions will be pretty much standardized. They don’t want to have a “hard” exam in which only 40% pass and an easy exam in which 70% pass, that’s bad for business. They make 2 curves so they both have similar pass rates.</p>

16

<p>Thanks hypnotoad! Man you’re all over the place with AP Chem haha.</p>

17

<p>Wow I did so terribly on the first three questions. I’m hopeful that question 4-6 will make up for that. I know I did well on the MC so maybe I could still pull a 5 if the curve is favorable enough.</p>

18

<p>WHATD YOU GUYS GET ON THE AP?! got a 4 :D</p>

19

<p>5! Which was totally unexpected for me :)</p>

<p>Does anyone know what percentage of AP Chem (typically) get a passing grade (3, 4, or 5)?</p>
