<p>@ stix2400 - two resonance structures for incomplete Lewis
sucrosesolution is not volatile.
hcl dissolves completely.
ch3oh is the polar molecule.
ccl4 is nonpolar liquid.
nh3 creates weak base.
crucible is not needed for titration
9 moles of 02 in one of the combustion equations.
for some reason i also remember 0.0500 times 6.02 times 10^23 (1.12 liter thing at STP)</p>
<p>last question answer was 230 kJ (13 times 18)
there was a question with multiple proportions theorem involved. something with Fe and O and diff compounds with them.
0.01 molar of nacl creates neutral 7 pH solution because of equal amounts of H30+ and OH-.</p>
<p>one of the questions also involved an answer that was like " <7 ph"</p>
<p>oh wait…</p>
<p>I can’t believe… I misread the 1.12 Liter thing. NO! That was an easy question and I missed it. </p>
<p>what about the question about saturated NaCl solution? What happens if you add more NaCl?</p>
<p>zinc and hydrochloric acid question created the biggest increase in entropy?</p>
<p>Ammonia does have an order(and it’s really really strong)… The sugar one didn’t…</p>
<p>Stix, I said the concentration would stay the same…</p>
<p>and yes Feynman</p>
<p>the benzene question was “TF”
the isotope element X has a weight of 9</p>
<p>i don’t think I have almost any mistakes i just wish i went faster grr… =/ im gonna end up getting like 50ish correct and like 20 blanks…</p>
<p>btw why cant ch3oh be the weak base? im prob just mixing it up with acetic acid though.</p>
<p>exactly, so sucrose WAS the answer to the first part of that thing. anybody remember more of the TF/TF/CE questions?</p>
<p>yeah ch3oh was a diff question i think. ch3oh is an alcohol…it was the polar molecule.</p>
<p>there was a question about something that had covalent and ionic bonds it was like “NH4Br” or something.</p>
<p>huh? what was sucrose an answer to? I don’t remember it being correct for any of them.</p>
<p>sucrose is the one that does not create the odor. there was a question about what DOESNT create an odor when mixed in solution.</p>
<p>and yeah, NaCl added to a saturated solution will do absolutely nothing because it will be left in standing as precipitate. will neither affect density or concentration.</p>
<p>oh right haha. I’m getting backwards, thinking that it asked which one did have an odor.</p>
<p>to double check: there was one question asking what DOESN’T have an odor, and but there wasn’t a question asking what DOES, right?</p>
<p>Are you sure the KI one is using a “sieve?” I put the water one, because logically, KI is the only one that would dissolve in water, whereas Fe and sand would not, thus extracting the KI</p>
<p>i am trying to think of all the number answers on the test</p>
<p>anybody recall 2 L times 740/760 times 273/300? (original volume times pressure1/p2 times temp2/temp1)</p>
<p>@ bonduck nahh water would not be the best method. crap could stay in water. you need a sieve to filter. a sieve is a type of net. i didnt know that either but i was looking for filtrating device of somekind and that is the only that could have been one.
also, no there was no question on what actually gives off an odor.
i spent so much time memorizing colors and all to no avail.</p>
<p>what do you guys the roundabout curve will be on this exam?</p>
<p>I think that’s what I got – its hard to recall exactly what fractions I got for that question</p>
<p>Other stuff:
I also got five T/T/CE’s</p>
<p>yep to 740/760 time 273/300.</p>
<p>And i thought there was only one odor question.</p>
<p>Wait, why would it stay in the water?</p>
<p>“KI, which is a polar, ionic compound, will ionize and dissolve in water. When
KI dissolves in water, it ionizes to K(+) and I(-).”</p>
