*** November 2013 - Chemistry***

<p>The other one was separating sand and salt</p>

<p>what’d you guys get for the light ones?
i remember one was about global warming, another about ozone, and i forgot the third</p>

<p>and also the density problem where there answer choices were like 2 x 32, (1/2)x16 or smth like that?</p>

<p>Was one 0.003 mol?
The big redox question (n.55) where we had to balance it…What was the answer? It was like
Ag + … —> NO2 or something like that
For burning glucose or something, was it 602?
What was the one about silver nitrate? It had like it will be white or something…I chose colorless in pure water as the answer to that question. I’m not sure, though.
Was one: Cr2O7 or something becomes Cr3+ ??
Which had a blue color: KOH?</p>

<p>I think the blue one was the one with Copper. Also, what was the sand and salt one?</p>

<p>The funnel filter thing could also be used to separate them after it has been in solution and rinsed then filtered, i don’t remember seeing a magnet</p>

<p>The solution is colorless & the precipitate is white</p>

<p>The magnet was choice D.</p>

<p>Was one 0.003 mol? For that one i got 0.0300 mol.
The big redox question (n.55) where we had to balance it…What was the answer? It was like
Ag + … —> NO2 or something like that. For that one i got only 1 NO2- </p>

<p>For burning glucose or something, was it 602? Yeah, i also got 6O2. </p>

<p>What was the one about silver nitrate? It had like it will be white or colorless. If you’re talking about the one that reacts with nacl to form agcl, then the precipitate was the “cloudy white” option. </p>

<p>Was one: Cr2O7 or something becomes Cr3+ ?? For this one i chose fe2+ to fe3+. Not sure why I did that…do any of you remember if the question was which one was oxidized or was it reduced?</p>

<p>Which had a blue color: KOH? No, K is purple. The answer should be the one with copper.</p>

<p>@ccuser101
The Cr2O7 answer was for a question that asked which one of these reactions is an oxidation reduction reaction and the one with Cr2O7 was the correct answer (pretty sure that was the question). I got 6O2 for the burning glucose question. I also got 0.0300 mol for one of the questions… I don’t remember which one. For the one about NaCl, I think it asked which substance has to react with it to form a cloudy white precipitate and the answer was AgNO3 or something with Ag in it because AgCl is insoluble. I also remember getting 4 TTCEs? We need more people responding to this thread, Math II has like 25 pages already lol.</p>

<p>@lebtony</p>

<p>Darn, you’re probably right. I erased my answer for CrO7-2 and chose the Fe one. </p>

<p>I also remember that for one of the answers I chose 2.0 * 10^(-4). I do remember that in that question they gave the molar mass as 100g/mol and there was .02 g of that substance.</p>

<p>@mistswirl Yeah, I remember getting 2.0x10^-4 too… it was like (2.0x10^-2 mmol)/100mL because it was diluted or something like that. There was a separate question with Fe2+ being oxidized to Fe3+ and that was also a correct answer I remember. We might be talking about two different questions? One had Cr as a correct answer and another one had Fe2+.</p>

<p>@lebtony</p>

<p>Ah, that would make more sense. I always get these questions mixed up xD</p>

<p>I’m trying to think of more questions but I can’t seem to remember any… Seems like not a lot of people took the november chem sat. :/</p>

<p>I forgot the one with Fe2+, but the one I chose as answer had specifically “Cr3+”. Was that one of the answers?</p>

<p>what was the density one with 2 x 32 and (1/2) x 16 and such?</p>

<p>i think i got 2 x 32</p>

<p>Hey, I took the SAT Chem in Oct, and I definitely missed 4 questions. </p>

<p>I still made an 800. Hopefully this should give you a good idea of the curve. Good luck guys.</p>

<p>@chessy18</p>

<p>Thanks for letting us know!! I was worried about this month’s curve because I had actually taken the SAT chem in June and ended up canceling my score because I thought I’d missed a lot of questions. Then I heard that the curve was better than usual and regretted canceling…haha</p>

<p>the one about gaseous & removing electrons was ionization energy</p>

<p>@Girlygirl22, yeah I got the same answer.</p>

<p>The question with 2 x 32 asked what is the molar mass of a gas that is twice as dense as oxygen gas (O2). Since the molar mass of oxygen gas in 32 g/mol and it is twice as dense you multiply that by two.</p>
