The October CHEMISTRY SATII Discussion

<p>So, howd you feel about the test??</p>

<p>I thought it was kinda hard. the concepts were easy, the time was tight. I skipped 9 and prob got 1-4 wrong..
one kid said he skipped 13. another said he skipped 19. idk
ugh.</p>

<p>Hey how many T,T,CE's did you guys get?</p>

<p>Ughh Chemistry was very hard. A lot of other kids who took it were saying they failed it during the break.</p>

<p>I just wasn't that well prepared for it, I probably skipped 9 and got at least 4 wrong. I think I got 3 T,T,CE answers, not sure</p>

<p>a lot choices are F,F and T,T</p>

<p>It was hard and I definitely didn't have enough time. I think I skipped around 7. I also think I got 3 T,T,CE</p>

<p>Hmm did you guys get 3 or 1 for the NO2 coefficient in that Redox reaction?</p>

<p>About the this BECAUSE that questions, do they count totally wrong if you miss one part of it, or are they scored by each part? I'm guessing the former.</p>

<p>Was that the third question about coefficients? If it was, I think I got one . . . for the first two I got 3, didn't really check my work, hopefully those were right</p>

<p>anyone remember that big redox one?</p>

<p>I got 3, 3, and 1 for the coefficient problems. Four TTCE answers.</p>

<p>Can anyone remember the first 2 coefficient questions? I'm not sure that's what I got... I also got Four TTCE answers tho.</p>

<p>Oh and did anyone get the following:</p>

<p>Two gases are injected into a flask. Partial Pressure is determined by the following:</p>

<p>I. Mols of gas injected
II. VOlume of Flask
III. Reaction between the two gases</p>

<p>Does the reaction play a part in addition to choice I? I know the volume dopesn't do anything. Oh and were the lab equipment used:</p>

<p>Sand + salt = filter paper funnel
Copper/Iron = Magnet
HCL+H2 = Water trough</p>

<p>Hmm. Why wouldn't the volume of the container do anything?</p>

<p>It's true that if a mixture of two gases had partial pressures of, say, 100 torr and 200 torr in a 1 L container, the pressure of the first gas would be 1/3 of the total pressure regardless of the volume. But if the container were instead 500 mL, wouldn't the pressures increase to 200 torr and 400 torr respectively, meaning that while the proportions wouldn't change, the magnitudes would? I could be wrong, though.</p>

<p>i said it would be I,II, and III for that one; not too sure though
i had the same thing for the lab equipment</p>

<p>i think i only got 2 T,T,CEs</p>

<p>feeling really bad about the test now</p>

<p>Oh, and I said the reaction also played a part, since for example you could have a reaction whose products had a different number of moles of gas.</p>

<p>I got 4 T,T,CE's... ugh there were a couple of F,T's and vice versa which made it really ez to avoid the CE bubble. Hopefully i still 800 it- it's a 5 question wrong curve right?</p>

<p>Somewhere around there.</p>

<p>what was the answer to the one about: which of the following would dissolve most readily when heat is added</p>

<p>Can't recall. Do you remember what the choices were?</p>
