<p>so does barrons, the oxidation definetly occurs in the anode</p>
<p>Why did people do 8? 7 was, like, the easiest question I've ever seen on any Chem FR. 1/4 of Question 7 was it giving you two masses for isotopes and telling you to find the element!</p>
<p>:)</p>
<p>uhh...#8 was really easy too... I personally did #7, but I probably would have gotten the same score on either one.</p>
<p>I can't wait till we start discussing the the Free Response!!! I want to know if I got all of the last part of #1 right and the second-to-last part of #3 right. And those lovely reactions...</p>
<p>dammit, I just realized I forgot to write all my answers down on that green insert that goes to our teachers. Well I guess I won't know how I did till july...</p>
<p>OMG - I can't believe that AgCl is fricken WHITE. I said it was BLACK. I failed.</p>
<p>I was so prepped...but I would swear now that I got a 4.
I got such a high 5 on the 2002 practice...but then this one came and killed me.</p>
<p>And I had NEVER learned about formal charge. That was aggravating.</p>

<p>I made the exact same mistake, and (to make things worse) we even did a lab last year involving AgCl... I just couldn't remember. I can live with a 4, though.</p>
<p>lol. I don't think anyone covered formal charge that well...I think we will all be surprised when the scores come in. APs can go either way...</p>
<p>We covered formal charge for like a whole day... 1st term...</p>
<p>:</p>
<p>the only thing my teacher did for flame testing in the burning the splints with salts of potassium and soidum, we never did it with gases so im pretty sure i got thaT whole part of #5 wrong.</p>
<p>i had no idea what to do with that...so i made up stuff assuming burning split has O2 somewhere in there....lol...</p>
<p>For the 1st FRQ, did ne of u get 6.15E-4 for the concentration of H+. I think I might have messed up because I forgot to convert mols of NaC3H5O2 to Molarity.</p>
<p>Sry for the technical reply</p>
<p>I'm fairly confident about 3, 4, 5, 6, and 8 on the free-response, and will post my unofficial solutions tomorrow.</p>
<p>Is it potassium sulfide that is black or is it magnesium sulfide?</p>
<p>....it is Ag2S</p>
<p>EDIT: "Ag2S is extremely black, and hard to dissolve"</p>
<p>Yeah, I got that one wrong.</p>
<p>I had a study session with some of my friends on Monday night, and my friend had this sheet called, "Things to know for the AP Exam that I do not know already." So whenever we veered off Chemistry, she pulled us back in by reciting flame test colors off of the sheet. So I nailed all questions having to do with colors besides that one.^</p>
<p>what's the rate order for 3?
is it first order for both?
i think i screwed that one up....</p>
<p>the rate order was one for both of them.. and then the vertical axis was
ln[h2o2] .. one of things i had learned the night before.. didn't really know u can have third order for anything.. did ppl get the NaS thing as having no solution in that #8 frq thing.. did anyone get like.. 3.72 for the frq?</p>
<p>people keep talking about nailing colors on flame tests, I didn't have any flame tests that produced colors. I only had the wodden splint thing. I hope I didn't skip a page or something.</p>
<p>No, there weren't flame tests, there was just the glowing splint stuff.</p>
