<p>There is nothing wrong with saying an excited atom or an excited electron. Maybe if it said an excited proton or neutron I would agree with you but there is nothing wrong with saying an excited atom.</p>
<p>clicheusername57, I specifically don’t remember any volume for the buret or graduate cylinder question. If they had listed a volume, then it would definitely be the buret because in that case it would have better markings, but it’s not true for all sizes.</p>
<p>Tux are you counting the ones of which you have different opinions from everyone else? I am not saying you are necessarily wrong or right for them, but there are 3 or so questions that are pretty up in the air in terms of the answer right now.</p>
<p>EDIT: you might be right for that. I thought someone mentioned that it was 50-ml, although I don’t remember if they included measurements or not. Can they omit questions because they are too vague/two possible correct questions?</p>
<p>for the buret/graduated cylinder, im pretty sure they said to measure out 27 ml using a 50 ml buret, grad cylinder etc… not sure though</p>
<p>Actually, I skipped 2 and got 3 wrong. Yeah, I am counting everything. I realize I read too much into the question about neon. I had the right answer first, then changed it. The lab safety question I’m almost sure about, even though there is some concern over that. I haven’t counted the buret-graduated cylinder question yet, but if it’s wrong, then one point still won’t keep me from getting a good score.</p>
<p>Pretty sure the question for the lab was what is correct lab procedure, and it was I and III. Always wear eye protection and never add acid directly to water.</p>
<p>I don’t think the wording was “always pour water into acid.”</p>
<p>Always I don’t quite remember, and didn’t it say what kind of acid it was?</p>
<p>Wow, good job then, considering you have valid arguments for most of the questions up for debate. Bumb about them later rescinding questions though, can they do that - do you know? I was pretty sure about the safety one as well… is anyone sure on the wording, did it say don’t pour water directly into sulfuric accid, or did it say don’t combine water directly with sulfuric acid or what?</p>
<p>Edit: It was about sulfuric acid, and i’m pretty sure if was something else than “never pour water onto sulfuric acid” idk I remember questioning that wording the first time someone said it on here</p>
<p>wow, nice… i have 6 wrong and 0 omit, that’s including those 3 or so questions that are questionable as part of my “wrongs”. Does anyone know how the curves are determined?</p>
<p>For the lab safety question, it was about correct procedure as yunu said, good catch there, I didn’t realize that part even though I knew the question was about correct procedure:</p>
<p>
</p>
<p>I is correct. You never add water to acid as it isn’t part of correct dilution procedure and such. II you never do because it can cause contamination since the chemical has already been exposed to air. III is a given; you must always wear goggles. So, the asnwer is I and III.</p>
<p>If they mentioned a specific acid, which I’m pretty sure they didn’t, then it was just to trick you. It’s the same with all acids, and it would be even more correct with H2SO4 because it is a strong acid.</p>

<p>Oh damn…and it was sulfuric acid that they mentioned I am 100% positive :(. Oh well.</p>
<p>Our AP Chem shirt this year was “Real Chem Students (I guess it is more politically correct than “Men”) Add Water to Acid.”</p>
<p>I kind of grinned when I saw that question.</p>
<p>7 wrong, including 2 controversial ones, 0 omit… 
i’m kinda nervous about the curve. Is it harsh usually? There are rumors that 4 wrong =800, but I have no idea. Anyone know?</p>
<p>EDIT: hahhah Jenkster thats COMPLETELY something my school would do. We are making tie-dye chem T-shirts on friday and I am totally going to suggest putting that on there…</p>
<p>Aw, you are still in school?</p>
<p>6 total wrongs, 3 up in air, and 2 omit…any score calc?</p>
<p>if you got all of the questionable ones wrong, your raw score would be 85 - 2 - 9 - (9/4) = 72 …i would bet that you got around 750, but you can never tell for sure</p>
<p>78-85: 800
76-77: 790
74-75: 780
72-73: 770
70-71: 760
68-69: 750
67: 740
65-66: 740
63-64: 720
61-62: 710
59-60: 700" thats for chem, they didnt specify what year the book was from though.</p>
<p>That’s the curve for 2005 from the CB book. You’d have a 72 raw score if you got all the questionable ones wrong as well as the ones you know for sure. According to this, it could be a 770, but I’d bet around a 750 or a bit higher.</p>
<p>did anyone here, who took the AP chem test in May, think that the SAT II was was about as hard? I thought the AP multiple choice was easier than the SAT II…maybe I’m just weird</p>
<p>AP multiple choice had harder math.</p>
<p>On the other hand, SAT II had lots of easy stoichiometry.</p>
<p>you’re right, but on the AP test, I had 25 minutes left over to check over what I had, on the SAT II, I got screwed for time</p>
