<p>So this was like 10 pages ago or something, but I’m pretty sure that Nitrogen gas only uses London forces, since it’s non-polar.</p>
<p>w2g 10char</p>
<p>Global warming question was one of those true-false-CE questions. It followed something like:</p>
<p>T/F Carbon dioxide contributes to the greenhouse effect.</p>
<p>T/F Carbon dioxide forms an acid with water.</p>
<p>CE.</p>
<p>I think I put T,T and no CE.</p>
<p>Does anyone know how many you can get wrong and still get an 800?</p>
<p>2 (10 char)</p>
<p>so what would be my score if i missed around 8 questions?</p>
<p>and for you guys who felt prepared for this test, what prep books did you guys use?</p>
<p>thanks!</p>
<p>what is the name of the change from solid to vapor? </p>
<p>heat of ____ whats it called again?</p>
<p>sublimation</p>
<p>is CH4 a lewis base?</p>
<p>for that one true/ false/ ce problem?</p>
<p>^^no no no</p>
<p>i skipped alot of problems</p>
<p>student8181 it was heat of fusion</p>
<p>the math without a calc really screwed me up</p>
<p>whats the minimum amout you have to get wrong for a 700</p>
<p>Wowow I don’t know how I messed up the distillation question, I put buret LOL. I somehow had this image of titrating with ions that would form an insoluble precipitate with Cl- or Na+. I’m an idiot lol. I also mis-read the temperature one, I thought that the density would change (forgetting it was fixed container). Oh well, only -2 so I <em>may</em> squeak by on an 800.</p>
<p>However, what did people get for most electronegative element, it was between C and Cl for me.</p>
<p>i think i put Cl</p>
<p>snap660, it is heat of sublimation. heat of fusion is from solid to liquid.</p>
<p>I looked it up, the answer is Cl, I really hope I picked that one. I’m worried that I chose C since it’s higher up</p>
<p>what did you guys get for the question that asks about what concentrations will be the greatest when Na2SO4 is in water?</p>
<p>would it be Na+ and SO4 2- ?</p>
<p>^ yea, those are the two ions.</p>
<p>Yes, that’s what I put</p>
