<p>I had about 3 minutes left for SAT II. Don’t remember for chem.</p>
<p>What was the answer to the question near the end asking for the empirical formula of Cd,O, and H? 77% Cd, 22% O, and 1.4% H would mean it is Cd(OH)2, correct?</p>
<p>Tux yeah I predicted less than the book had said especially because I probably made a few stupid mistakes I can’t think of right now. </p>
<p>Has anyone taken the chem SAT before this. Was this more/less difficult than previous tests?</p>
<p>I took May’s chemistry SAT, which I’m getting rescored. That’s a long story in itself, but May’s test had easier T/F, but more diverse MC than June’s test.</p>
<p>If a question had a really iffy wording
Do we just suck it up and get it wrong
Or can we take it up to collegeboard and like write a letter?</p>
<p>SAT II is definitely easier than AP test in regard to what percent right you could get.</p>
<p>yeah babeexphat i bump about that one. a few of them had really questionable wording, of which im pretty sure I answered correctly, but still it confuses me. And does anyone who wasnt here yesterday remember if it was 3.22 atoms or molecules? After everyone said molecules last night I was pretty confident thats what it said, but after my chem class today the majority said it was atoms…although 1 or 2 said molecules… anyone else remember??</p>
<p>im almost 100% sure it said molecules</p>
<p>thnx im just going to assume it did, that’s what the resounding answer has been from here</p>
<p>Sorry guys, the 66 questions I posted before was by courtesy of Pinki10583. Credits go to Pinki on that one. But you can already see that as the updated version is already out, lol.</p>
<p>updated version?</p>
<p>I meant what Pinki posted on page 34 is updated compared to what I posted on page 33. </p>
<p>Although Pinki’s page 34 update still needs to be fixed…</p>
<p>it is definitely molecules. Not because I remember vaguely it said molecules, but it just doesn’t make sense to ask for atoms.</p>
<p>this might be a dumb question but can someone explain to me how to do this problem?</p>
<p>3) What would be the formula of CxOy if it is added to one mol of oxygen and produces .5 moles of carbon dioxide?</p>
<p>C2O3</p>
<p>thanks</p>
<p>Are you sure it was 1 mol of oxygen to .5 moles of CO2? That wouldn’t give you C2O3.</p>
<p>Yeah I noticed that too jenkstere. And afruff why doesn’t atoms make sense? There are 3.22 molecules in 22g CO2, but for every molecule there are three atoms, so in 22g there are 6.22x3 atoms.</p>
<p>Or in 7 g nitrogen (N2) there is 1/4 of a mole of molecules x 2 atoms per molecule = 1/2 mol</p>
<p>im not saying it was molecules/atoms cause I don’t remember but I think they both make sense</p>
<p>You’re both saying the problem wrong I think.</p>
<p>@clicheusername57</p>
<p>It does make sense, but it’s just a weird thing to ask. There’s still a possibility it said atoms.</p>
<p>—sorry i repeated previous post by accident–</p>
<p>Yeah, I just remember it cause they had those on the barrons practice test. I also think they asked on another question how manay atoms are in like x(OH)3 or something. Or maybe it was like how many atoms in x2(SO4)3.not sure, could have been a practice test.</p>
<p>I actually remember that it was molecules because I caught a mistake in that problem.</p>
