<p>oh crap. if I got 11 questions wrong and 3 blanks, should I just cancel my scores??? I just want a 750...</p>
<p>Kelper that one was the last T/F type question.</p>
<p>I put FF for that one. You are right. The speed of the molecules are only dependent on the temp and that question said temp. was the same in both containers</p>
<p>It said "same velocity" or something like that, so temperature had to be the same in the two containers.</p>
<p>the speed of molecules is dependent on weight and temperature, but i think the statement was asking whether or not 2 species of gas molecules at the same temperature have the same average kinetic energy. it is true because temperature = avg kinetic energy, regardless of weight. the tricky part was the second statement, which asked if temperature is the sum of the kinetic and potential energy of a gas. i said TTCE, but i think it was TF. any thoughts?</p>
<p>It asked if total energy is the sum of kinetic and potential energies, and that is true.</p>
<p>I just put TT, not CE.</p>
<p>yeah, you're right. its probably TT. ahhhhh. In all of the practice books the TF section is so easy and it was so hard on the actual test.</p>
<p>hmm. what's a good score if ur aiming for the ivy leagues.</p>
<p>is 770 okay?</p>
<p>Kelper:
I remember distinctly drawing a picture on the test for that question, one of the First Container and another of the Second Container (Twice the size of the First) and got that the pressure was greater in the first container since it said that temperature and the amount of argon molecules was constant between the two, therefore since T is negligible and PV=PV the first container has a higher pressure. As for the second part, I think it said something about the average velocity of the molecules being equal between the two containers which was true since they both had the same temperature. I don't remember whether I put a CE. I think I did...</p>
<p>Fully agree, Bronx Science. </p>
<p>Scott Kim: Do you really need to ask that question? You know damn well that a 770 is perfectly fine for any school you apply to. Honestly, I know I'm not going to get close to that (I'm speculating a 710-720), and I don't really care. I think that so long as they see 700+, no problem.</p>
<p>can we get a compliation of the questions?</p>
<p>i thought it was opposite, where is said increasing ionic character?</p>
<p>ekb it should be like this N2<FCl<KO</p>
<p>Im 100% sure KO is the most ionic and out of all the choices, choice A ONLY had KO the greatest.</p>
<p>so, you forgot to put in the change of phase... vapor at80 degrees, so add 2000 for the change...</p>
<p>For the KO one, A is the answer I got too.</p>
<p>And for the change of phase, did it specifically say that it did change phase?</p>
<p>^ any thoughts? would you cancel your scores if you know for sure you have 11 wrong and 3 omits? aiming for above 700...</p>
<p>thanks</p>
<p>For the ionic character, what everybody else says is correct.
I just thought about the electronegativity differences between the two elements it gives. Like N2, lowest since it's the same, and KO highest since the two are on different sides of the periodic chart. I'm angry that I put graduated cylinder instead of the pipette thingy. I didn't even know what that picture was, and I remember using it all the time in labs. I wish they had the words by it because I would've picked the pipette because I know they have exact measurements.</p>
<p>I already know I missed a couple from absolutely silly mistakes, and I know it's going to haunt me. I shouldn't have played DOTA the night before.</p>
<p>Well, that comes out to a 750 in Kaplan, azalea.</p>
<p>I have a question. </p>
<p>For the lab equipment question about preparing a solution, was it a beaker?</p>
<p>Was it the NaCl solution? The answer was either the graduated cylinder or volumetric flask. It was the volumetric flask.</p>
<p>How are you to but solution in a Volumetric Flask? Isn't the neck too narrow...?</p>
