<p>How accurate are the score charts in the review books? Like princeton…</p>
<p>I assume velocity to be the last option that couldn’t be remembered earlier…However, velocity is affected by temperature.</p>
<p>So I know I skipped 2 (the very first question and the spectator ion one) and I definitely got 2 wrong (the N2 London Dispersion question and the which one is not found in nature in elemental state one). I might have gotten at least 2 more wrong because of calculation errors, but I think I have a shot at 800. What do guys think the curve will be? The barrons book say -10 is 800, but I think it that’s too generous (then again, their tests are prob harder than the real exam). Would -6 for 800 sound like an accurate curve?</p>
<p>…I give up…sigh.</p>
<p>Was the answer 0.5 mols for the C + O2 –> CO2 question?</p>
<p>violinplayer that is right</p>
<p>^Yes.</p>
<p>****, looks like I am condemned to a 790 according to the released BB test. Anyone know the curve for last year’s June Chem Sat?</p>
<p>It’s average velocity that isn’t influenced by temp. as it’s only affected by molecular mass. Density (mass/volume) is influenced by temp because volume is affected by temp.</p>
<p>@shawnwhite313
that was my reasoning too. but everyone else is saying its volume!
???</p>
<p>but shawnwhite they said that temperature was kept constant</p>
<p>Is a -5/-6 still an 800?</p>
<p>@altamash
if temperature is constant, say 25 degrees Celsius, then the KE would be the same for all particles. But the particles differ in molar masses, so wouldn’t that determine the velocity?</p>
<p>No, they said that given a constant volume…</p>
<p>@vbpointer42: The problem was inquiring about a specific sample of gas.</p>
<p>
</p>
<p>Um what? The whole question was which of the following isn’t temperature dependent…?</p>
<p>sounds right but i put density so who knows?</p>
<p>Everyone go here and we can discuss:

<p>i think i am talking about a different question</p>
<p>so far 4 wrong. and I THINK I skipped 3. I would be so happy if that’s all I got wrong :D</p>
<p>An iron mesh screen rusts faster that an iron block BECAUSE an iron mesh screen has more surface area than an iron block.
I got FT. someone mentioned before in the thread that it was TTCE. but the rate of rusting doesn’t change for the shape of the iron, does it??</p>
<p>The amount of Fe contacting oxygen in a reaction increases with more SA. Thus, it would technically be of a higher “concentration” and rust faster. That’s just my thought process though.</p>
<p>the iron one is TTCE</p>
