<p>Do we have to know about hydrolysis?</p>
<p>We’ve looked at hydrolysis of salts, so yes.</p>
<p>We’re on acids and bases right now. We still have electrochem and thermodynamics to go through. We’re probably going to have to do some self study >.<</p>
<p>Finishing electrochem (last topic) after spring break, then review! </p>
<p>We did all the equilibrium stuff in second quarter, kind of rare?</p>
<p>ditto tillie. will be reviewing a lot over spring break. wrapped up chemical kinetics and spontaneity just a few days ago.</p>
<p>are u guys using Barrons? I have PR but it doesnt teach me anything beyond the super basics</p>
<p>i.e. only basic ICE chart for acid/base stuff</p>
<p>no variations for buffers or special scenarios</p>
<p>I’m just using PR as a very basic review and supplement to the main book. The practice exams are good though.</p>
<p>is anybody using the barron’s ap chem review book?
my parents told me if i finished it i could get pr 
because according to everybody on cc pr>barrons and my parents don’t feel like returning my barron’s book…
but anyways, is there a mistake in the first diagnostic problem of the first diagnostic test in barron’s?
because it says that the frequency is 3.0x10^15 hertz in the problem, but if you look in the answers, the book calculated the problem using 1.0x10^15 1/s (or hertz). is this a mistake or a weird conversion that they did without explaining…?</p>
<p>Is PR’s section MC good markers for if you’re mastering the content? I know using PR without a textbook is foolhardy (it makes me rage how little explanation is in that book), but it seems as if the q’s at the end of each chapter require a bit more thinking than regurgitating the theories listed.</p>
<p>We finished the curriculum last week. After spring break, we’ll have our exam on the last few chapters and have our final.</p>
<p>We have to do electrochemistry and then we’re done. :)</p>
<p>we finished everything; i just realized that i forgot everything about thermo and rate laws and equilibrium though</p>
<p>We’re finishing our whole Thermo unit with electrochem right now. We’re going to spend the next month reviewing and hitting a few isolated labs/topics… I know our teacher mentioned a mass spec…</p>
<p>Does anybody know how much Organic and Nuclear Chem we need to know for the exam?</p>
<p>^ Close to none. No FRQ cover those topics and you can expect less than 5 MC.</p>
<p>
</p>
<p>From what I can tell so far, it does seem to see if you’ve mastered the content. I actually haven’t done any of the reading review yet, but it definitely isn’t just plugging in numbers.</p>
<p>Yeah, I’d suggest reading through the nuclear chemistry at least if you have time because they are simple concepts on the test, but very little of that is tested on the exam.</p>
<p>what book (if any) can teach me how to do all of the math stuff (i.e. buffer/titration problems) on the FR portion of the test? PR def does not do this.</p>
<p>I got 5 steps to a 5 from my library the other day and it seems like it has a bit more of an explanation in there. However, I learned it mainly from taking the practice tests. If you know the answer, you can learn how to do the problem and why.</p>
<p>I’m stuck on a practice AP problem. Help D=</p>
<p>H2C2O4 (oxalic acid) <-> 2 H+ (aq) + C2O4 2- (aq)
Given overall K (…overall?) = 3.78 x 10^-6</p>
<p>What volume of .400 molar NaOH is required to neutralize completely a 5.00 x 10^-3 mole sample of pure oxalic acid?</p>
<p>Um, does the mol of oxalic acid also apply to H+? If so, why?</p>
