<p>ink by distill (wrong)–>chromatography
water and ethifej (Distill)–>fractional distillation
sand and salt (filter)–>dissolve in H2O, then filtration
h20 cryatal (hydrate)–> like CuSO4 5H2O
H and metal (hydride)–>like LiH, CaH2
Tin for more ox states–>?
h20 add salt … you get lower freeze pt (right), higher density (i put false) so just III but i think it might be II and III–> NaCl soln and H2O–>NaCl soln has lower FP and higher density
CO2 not harmful–>OK
7 carbon atoms (last question) –>?
separate by evaporation (salt)–>OK
mendelev … T F–> M predicted Gallium
3 TT CE’s in a row in second column
only one TT CE in the first column
one TT CE was it was about evaporation and not having enough energy and they have less temp–>looks correct
NO2 everything has an unpaired–> NO2 is a radical molecule
hydrocarbon- organic –> only has H and C</p>
<p>I REMEMBER( took it an hour ago!)</p>
<p>there were a lot of As in a row on the bottom of first column.
1.triple bond: N2
2.polar: NH3
3.180 degrees: CO2 –>(N2 is not considered to be linear due to two atoms)
organic compound: hydrocarbon
phase diagram: C was triple point
phase diagram:E was critical pt
phase diagram:B was (one the line) boiling pt
reaction Fe2+ -> Fe3+ + e- was oxidation
other one was precipitation–>PI++ + 2I- –>PbI2
other one was …?–> CaCO3 –> CaO + CO2
3TTCE in a row on second column (one was catalyst)
balance for (NH4)2 thingie: 4H2O
i put n2o… but i guess it is n02. can anyone explain?–>NO2, radical molecule
highest pH: HOCL or H2PO4 or HC2H3O2 or NAOH or something–> NaOH</p>

<p>wat can i get from 6 blank and - 5 ish?
ugh does it worth not cancelling?</p>
<p>and for .1 M HCL, asking which is correct</p>
<p>it was ph=1, right? </p>
<p>the other choices were something like concentration of h+ less than cl-, or concentration of oh- greater than h+, etc</p>
<p>Ok good, I was just making sure. And then, there was one question involving
2Br+ + 2I- => 2BrI. I don’t remember it exactly, but what was that question asking, does anybody remember? I think I got it wrong, but I don’t even remember the question.</p>
<p>Lol I realized that I only had 10 minutes left to check my work, and I got really scared. I skipped the H+ + CaCO3 question, but since its the salt of a strong base and weak acid, wouldnt the result be CaOH and H2CO3, and since the Ca dissociates, it would be just I true? I’m not sure, but if that’s right, shoot me know, because, like I said, I left it blank.</p>
<p>H2plusO2left 1LO2
H+ + CaCO3 produces:
1 mol Ca2+
2 mol CO2
1 mol H2O anyone?</p>
<p>i believe it was (1) and (3), it couldn’t have produced co2, there wasn’t enough carbon to produce 2 moles of CO2</p>
<p>DAMMITTT, why am I such an idiot, can’t believe I put the wrong one for highest pH…</p>
<p>Haha, I skipped that one, too. Ran out of time…</p>
<p>teddybear i think you’re looking at a ~750 with that</p>
<p>Education: I said I only with the same reasoning. Carbonic acid would dissociate partly, no water involved…</p>
<p>teddybear i think you’re looking at a ~750 with that </p>
<p>No, I think more like 710-720 
though the curve might be a little more generous because this test felt harder… 730 at best, i’d say</p>
<p>So far I know I’ve gotten one wrong (The Bohr’s model one, the question asking for Hydrogens first ionzation energy, and I was too stupid to realize it was the line from 1 to infinity…) and I’ve skipped one. If i get a total of 3 more wrong, can I still pull off a 790? (I didn’t leave any more blank). I checked with other people’s answers, and I got, so far, everything I can remember correct.</p>
<p>Did anyone else put bba for the last of section one?</p>
<p>I don’t remember if I answered the equilibrium question or not… -5 or -6 depending on if I did. I really hope it has a good curve.</p>
<p>lol xkaramelle what the hell are you talking about the official curve is completely different from yours</p>
<p>isn’t 6 skipped and 5 wrong -12 from the total raw score= 85-12=73
the curve in the CB book says that it’s 750</p>
<p>edit: btw this might be a really stupid question but… the curve for sat ii chem changes for each test, right?
so like this time, the curve might be more generous?</p>
<p>shiet… 4 wrong til now</p>
<p>gahh i’m so annoyed. i knew everything but i didn’t pace myself and couldn’t finish. :(</p>
<p>^ Do you think it will be more generous this time though?? I didn’t think it was THAT hard…</p>
