<p>Anyone remember what letter was the 3.0 choice?
I know I chose a 3, but I don’t remember seeing two options :P</p>
<p>I believe 3.0 was D and 3.00 was E. That could be wrong though, I’m not entirely sure.</p>
<p>I also put TTCE for Le Chatlier’s principle.</p>
<p>I guess that’s why we had 5 TTCEs while others only had 2, GreedisGood? If I’m remembering correctly that you said you got 5 as well.</p>
<p>Yes you are remembering correctly, I had 5 TT CE’s</p>
<p>I’m fairly confident that the gas one was TTCE as well. If I’m not mistaken, II said that it shifts to the left to reduce the moles of gas, although I didn’t exactly read it very carefully.</p>
<p>I got 3 TTCEs but I left two out. Left the hydrogen absorbing energy one out. Here’s what I got:</p>
<p>“HCl conducting electricity” is TTCE</p>
<p>“H2O has a higher boiling than H2S BECAUSE H2S has a higher molecular mass than H2O” is TT. H2O does have a higher boiling point due to hydrogen bonding and H2S does have a higher molecular mass but the two don’t explain each other.</p>
<p>“Salt water and distilled water have the same boiling point BECAUSE salt water and distilled water have the same vapor pressure” is FF. Salt water has a higher boiling point and higher vapor pressure than water.</p>
<p>“Zinc conducts electricity better than Phosphorus BECAUSE Zinc has twice as much electrons as Phosphorus” is TT. Zinc conducts electricity because of the “sea of electrons”. Zinc does have twice as much electrons as Phosphorus but that’s not the reason why it conducts electricity better.</p>
<p>Isomer of hexane was 2-methyl pentane (choice D I think)</p>
<p>3.0 g/ml was the density for the solid, it was 3.6 g divided by 1.2 volume (3.00 is wrong, only 2 significant figures)</p>
<p>Best oxidizing agent is F2 (oxidizing agent is itself reduced, and reduction is gain of electrons)</p>
<p>The electric configuration of an atom helps us identify:
I. Ionization energy
II. Mass of the atom
III. Oxidation states</p>
<p>I and III only. III is true for sure and II is false for sure. There was only one answer choice that had III and not II and that was I and III.</p>
<p>That’s the one’s I remember, I’ll try remembering some more. Oh yeah, the one where it shows the picture of all the equipment and asks which is good for looking at precipitate, I put the test tube (choice A i think).</p>
<p>Crap…looking back on the Zinc one I think I got that wrong, because I think I said TF even though is it TT</p>
<p>What do you guys think will be an 800 on this test? Raw score of 79? 80? 81?</p>
<p>I put TTCE for the Le Chatlier one as well. That one and the HCl one were my two CEs (and I skipped the hydrogen one which was supposedly also CE).</p>
<p>There was another Part II about argon. Don’t remember what the first statement was, but the second said (I believe) that the average speed increases as the temperature increases. I think I put FT for it.</p>
<p>Does anyone remember the other answer choices for the question that asked which of the following scenarios had the greatest uncertainty?</p>
<p>■■■ i just realized i put F for the zinc having more electrons than phosphorus
because i was looking at potassium omgggggggg lmao</p>
<p>do you remember the one question with the
test tube buret images</p>
<p>it was like:
what is used for mixing and seeing a precipitate form</p>
<p>also another question was w/ like argon</p>
<p>the total sum of energy is kinetic + potential</p>
<p>Wait what, average speed doesn’t increase when temperature increases?!</p>
<p>Can someone help me out with a rough prediction of my score?</p>
<p>I skipped 12 and got maybe 2 wrong.</p>
<p>Thanks if you can help!</p>
<p>“The higher the temperature, the faster the molecules move.”
KE= 1/2mv^2. Increase temp, increase KE. If m stays constant, v must increase. So average speed(v average) should also increase. That statement was T. The other is also T, but it doesn’t explain 1. So I put T, T.</p>
<p>disregard that</p>
<p>Yes. I put FT. It said a higher freezing point when it should in fact have been a lower freezing point.</p>
<p>I put TT and no CE for the one smoochumkisses is talking about. I think the first part also said that KE increases with temperature. </p>
<p>Also, what is filter paper used for? I put to separate precipitates from the solution and to separate solids of different densities (as in chromatography, no?). The other choice was to separate immiscible liquids.</p>
<p>zach12, i said I and III… separate immiscible liquids and to separate precipitate from solution</p>
<p>i always though that total energy=final-initial and was a state function independent of the path.</p>
<p>wait…then which one are you talking about zach12 that’s false for I?
And to the filter paper one, I only put precipitates. You might be right though that it’s used for separating solids. I’m fairly sure its not the liquids one.</p>
