<p>THIS IS NOT A PREP THREAD- you are simply giving formulas that are GIVEN to you by the ap people</p>
<p>now if people asked certain questions that might help! so lets get it going</p>
<p>how much kinetics/equilibria will be on the test?-- free response q’s on them you think?</p>
<p>In terms of free response, kinetics is usually a pretty common problem especially in part where you get to choose one of the two problems</p>
<p>Just me personally, I think that an acid and bases problem, kinetics, and redox are going to be on the test. There might be a thermodynamics question.</p>
<p>And yeah, lets keep this thread for question and answers, not restating equations already given to you by the AP exam. Lets keep 'em rolling!</p>
<p>my prediction?</p>
<p>number one will be an equilibrium question… i know, i know… im psychic. what can i say?</p>
<p>organic chem–almost neverrr but its in your best interest to know how to identify different organic compounds by their name.</p>
<p>isomers might appear.</p>
<p>so when finding Ksp, its [s][2s]^2 if a product is two moles
but when finding Qsp, the extra two in the doesnt matter?</p>
<p>nvm. i know what it is</p>
<p>when you find ksp, you dnt know the actual concentration so you have to assume that the s is twice as much because of the balanced equation.
but when you find qsp, you already know the concentration, so there is no need to double</p>
<p>Typically, there should be at least one organic chemistry equation in the section where you have to choose 5 out of the 10 equations, but other than that, it actually shouldn’t matter. You could get a 5 w/o knowing anything about organic chemistry. </p>
<p>How do you solve Ksp questions?</p>
<p>That was the only trouble I had with Qsp problems, thanks.</p>
<p>How much with wavelengths is usually on the test?</p>
<p>So far I’ve heard two things that are no longer on the AP Chemistry exam. Last year (2007) was the first year where they stopped letting you choose between two different free responses, you have to do both. In addition, there are now 3 net ionic equations where you must do all of them instead of choosing.</p>
<p>solubility product is the measuring how soluble a NONSOLUBLE compound is.</p>
<p>Ksp = [product][product]
if you have
X–> Y + 2Z</p>
<p>then your
Ksp = [Y][2Z]^2</p>
<p>each concentration is “s”–for solubility</p>
<p>the test will either give you the Ksp value and let you solve for s, or vice versa. this concept is basically all math.</p>
<p>the practice tests ive taken didnt have a lot on wavelength.</p>
<p>The chemistry test changed huh? Well, I wouldn’t know since I’m studying out of 2006-2007 edition. And my teacher needs to be updated as well then too…</p>
<p>What things do we need to memorize? Like color tests, definitions, etc.</p>
<p>hi, y’all…I’m taking AP CHem on May21st…as I was also taking APES at the same time…so, do you know how different would the exam be? is it in general hard?</p>
<p>^^The test did indeed change. You can go on Ap Central for 2007 and 2007 Form B Free Response questions, all with answers.</p>
<p>btw, to get a 5, all you need is 66%.</p>
<p>I AM STUDYING OUT OF THE 06-07 EDITION AS WELL! princeton review…</p>
<p>i dont think its going to be that different</p>
<p>i have pr 06-07 too.</p>
<p>i know the barrons is harder than the real thing for other tests, but does this hold true for the ap chem?</p>
<p>My guess is: 1) Equilibrium/acid bass
2) galvanic cell
3) Enthalpy/entropy
4) writting equations
5)something basic…maybe empirical formulas and that stuff
6) structural questions…maybe lab based</p>
<p>i’m sure a lab based essay question will end the thing… and of course #1 is some type of equilib/solubility question, as always</p>
<p>
</p>
<p>I wish it was those topics, then I would ace it with ease.

Important Flame tests:
Li+ = red
Na+ = yellow
K+ = violet
Rb+ = purple
Cs+ = blue</p>
<p>Ca2+ = red
Sr2+ = crimson
Ba2+ = green</p>
<p>Just read it couple of times, important ones will get into your head like red, yellow, blue, green.</p>
<p>aaah what are the best AP chem books? barrons math 2 really made me waste my time so i don’t know if i should trust barrons anymore</p>
