<p>we're done with everything (even reviewing).
We used the Brown book and did 19/22 labs recommended by College Board</p>
<p>We're using the Brown book, and we've only got to chapter 16. My teacher wants to speed through the last few, and then start a cram review in the alst few weeks.</p>
<p>ack! you guys started reviewing already?! my teacher is so slow!......
we still have a few more chapters to go! :(</p>
<p>Just finished buffers and titrations..</p>
<p>It was easily the hardest test of the year! :(</p>
<p>Besides that, all my class has left is solubility constants and oxidation-reduction.</p>
<p>we're on the last chapter- thermodynamics. should be finished by next week and then we'll start reviewing.</p>
<p>We have 2 more chapters to go, and we cover one chapter in 3 classes.</p>
<p>thermodynamics then oxidation-reduction then review(?)</p>
<p>We're also using the Brown/Lemay/Bursten book. We just finished Kinetics last week and took our first of three Equilibrium tests yesterday</p>
<p>just finished gaseous equilibrium</p>
<p>Oh my gosh, our class is so far behind it's not even funny. Chapter 8 in Zumdahl & Zumdahl! Needless to say, I won't be taking the test D:</p>
<p>Just finished Solutions. Began kinetics a couple days ago... I feel my class is so far behind everyone else's. However, my school has a very high passing rate for AP chemistry, so that's kind of reassuring...</p>
<p>I'm using the Brown book. We just finished 17 (acid/bases). We have nuclear, organic, and electrochemistry left.</p>
<p>We aren't even going to go over different types of solids/crystals. Can somebody explain these? Something to do with "face"?</p>
<p>As far as hard things go, what seems to be the hardest single concept for the AP exam? For me, molecular orbitals are annoying. Remembering the diagram to determine paramagnetism for B,C and N as well as O,F, and Ne is hard and long and for 1 or 2 questions only. I just remember that B2 and O2 are paramagnetic.</p>
<p>I also think I'm going to forget what the variables in the "real" gas law equation are. I'm talking about the one where it accounts for gases settling and slightly clumping together.</p>
<p>Even if you forget, those things will constitute like 3 questions of the multiple choice at most.</p>
<p>electrochemistry, we'll be done by next friday</p>
<p>afruff23 - types of crystals (face-centered cubic, body-centered cubic, etc.) isn't on the test. (I can't remember if it's on the official syllabus, but it never shows up.)
By molecular orbitals, do you mean molecular orbital theory? (bonding orbitals and anti-bonding orbitals?) MO theory is definately not on the test. It is specifically excluded from the official AP syllabus.
The variables in the real gas law should be intuitive from looking at the equation (which is provided on the equation sheet). One term modifies the V - that's the term that compensates for the fact that molecules aren't dimensionless points but actually take up space. (The volume they occupy makes the actual volume slightly larger than expected.) The other term modifes P - that's the term that compensates for the fact motion of molecules (and therefore their pressure) isn't dependent only on kinetic energy, but rather is also affected by the attractive forces between particles. (The attractive force pulling molecules together makes the effective pressure slightly less than expected.)</p>
<p>Good, but I don't think you get an equation sheet for multiple choice where questions about the "real" gas law would come up.</p>
<p>btw, afruff23, van der Waal's equation is on the equation sheet. I highly doubt they will give you a noncalculator MC question about van der Waal's law.</p>
<p>we are in chapter 16 in zumdahl. we have chapter 17 and may be organic chemistry to review besides that we are done</p>
