<p>oh snap…harvard may be right. it’s total mechanical energy that’s potential+kinetic, not thermal energy…</p>

awesome separation of mixtures picture. immiscible stuff is separated apparently by something called a “separating funnel”</p>
<p>can I break a 700 with 15-20 wrong and 3 blank?</p>
<p>There were two different T/Fs that had to do with increase in energy and kinetic energy or speed. One was the one with argon, and the other was the one that I was talking about. The argon one was the last one and said that speed increases with temperature. The other one was one of the first ones and said something about kinetic energy + potential energy.</p>
<p>Do you remember more about the Argon question? I only remember a multiple choice question involving the molar mass of argon.</p>
<p>I just remember getting TT for the energy question. It stated something along the lines of increasing temperature increases the average speed BECAUSE the total energy of a system is potential + kinetic</p>
<p>And once again, does anyone remember the actual values for the graduated cylinder in the uncertainty question? It wasn’t the one with 18 was it?</p>
<p>I don’t remember the first part of the argon question, but the 2nd part said that increasing the temperature will increase the avg speed of the molecules.</p>
<p>Another T/F question that I just remembered: increasing pressure makes gases behave more ideally BECAUSE inc. pressure makes intermolecular forces more significant. I said F/T.</p>
<p>^^ Yup that’s right</p>
<p>@Potato that question said that increasing temperature increases total energy because energy = kinetic + potential. I said TT there too.</p>
<p>Is the uncertainty one you’re talking about the one with the 7.5 mL graduated cylinder w/ an error of .2 mL (or something like that)? I don’t remember the other choices but I think there was one that said 20 deg C with a 0.2 deg error.</p>
<p>zach, I put the 7.5 one.
7.7-7.5/7.5 x 100= 2.66% error
20.2-20/20 x 100= 1% error</p>
<p>You’re more likely to form an error with the 7.5 one, thus it’s the most uncertain. </p>
<p>I agree with everything else you put though.</p>
<p>Right, the 7.5 mL one was the answer.</p>
<p>Ah I misread what you wrote. My mistake.</p>
<p>Can someone please help me out?</p>
<p>Around what should I expect if I left 12 blank and got 2 wrong?</p>
<p>there was another one that had four images
a test tube, titration thing, buret, and a cup with a lid on the side and the questions said:</p>
<p>used to mix solutions and see precipitate form</p>
<p>I put the test tube for that by process of elimination.</p>
<p>i skipped 8 questions. What do you think my score range is, assuming i get less than 10 wrong?</p>
<p>@Azn: If you skipped 8 and got 10 wrong it’s a 730.</p>
<p>I skipped around 8 and got around 4-6 wrong so I’m hoping for a 750…</p>
<p>How about if you skipped two and got maybe 5 wrong?</p>
<p>how about if you skipped none and got 3-4 wrong?</p>
