June 2010: Chemistry

<p>its quite a stupid question but do u have to report all the SAT subject scores to college?</p>

<p>@teddy, it was my 2nd, but the first i took i canceled right away. i just took it for practice.</p>

<p>i just was pressed for time and made silly mistakes. i can only afford 17 of them according to the blue book</p>

<p>@ Fresh ; Yeah, that’s what I put. It was half-guessing, though, but I just thought conservation of energy or whatever. It was reminsicent of Hess’s Law?</p>

<p>For the Bohr questions, the smallest change was E? And for the ionization energy of H I put A ( ? Whatever the largest one was. )</p>

<p>Arrgggg That was my mistake. I thought it was gas not liquid…</p>

<p>What do you guys think the curve will be?</p>

<p>

</p>

<p>What do you mean?</p>

<p>i calculated how many i need to get wrong to get a 700 or above.</p>

<p>61 (raw score) = (82-x)-(.25x) | i did 82 because i skipped 3 questions</p>

<p>which equaled 17 (rounded)</p>

<p>were the ionization energy A and the excited B (the one with principle level 2?</p>

<p>75 to 77?</p>

<p>what would be the range for those scores you think</p>

<p>there was a t/f question about evaporation and entropy, does anyone remember the answers for that?
also the t/f one about catalysts/reaction rates, it was in the 1st column</p>

<p>It’s a phase diagram</p>

<p>The isomer one was 1 and 2?
Methanol’s density is 0.79?
CO2 is linear (180 degrees), not N2?
H2O + Na –> na oh h2 (1,2,3)?</p>

<p>yea i got 1 & 2 for the isomer, methanol i dont remember, CO2 is linear and thus 180.</p>

<p>there was a t/f question about evaporation and entropy, does anyone remember the answers for that?
also the t/f one about catalysts/reaction rates, it was in the 1st column</p>

<p>anyone?</p>

<p>I think the catalysts one was TTCE
Do you remember the question for evaporation and entropy?</p>

<p>The temperature of the substance decreases as a substance evaporates/Entropy increases as substances move to the gas phase.</p>

<p>I think it’s TT.</p>

<p>^ i guess false true…</p>

<p>For the titration question thing, what’s the answer? It said SOLID mixture of NaCl and NaOH, so wouldn’t a bunsen burner be useful? And what is going to be measured by an analytical balance? It’s not like the NaCl and NaOH is going to be easily separated is it? O.o</p>

<p>*guessed 10 char</p>

<p>The fact that it said solid confused me but i still ended up picking Bunsen burner which is probably wrong…</p>
