Official December SAT II Chemistry Thread

<p>it wasnt specifically the word AFTER, but the question pretty much implied that the reaction was already AT equilibrium...i cant remember the exact wording</p>

<p>what's the partial pressure of Nitrogen?</p>

<p>wait so how the **** is the graph suppose to look a straight line?</p>

<p>i think it was like 610mmHg??</p>

<p>for the equilibrium one, either it started low and evend out or started high. now i dont remember the quesiton but i put that it started low</p>

<p>no u got fooled i rememebr putting that then changing it cuz i got hella tricked</p>

<p>C2O3? (CxOy, remember that one?)</p>

<p>yep, 610 mm Hg, i was worried there was a trick there</p>

<p>wait so it was 610? and yea i put C2O3 also</p>

<p>it wasnt 610 right?</p>

<p>I remember one question was like SO2 + 2O2 = 3SO3</p>

<p>And it said that if you had one mole of sulfur dioxide and 1 mole of oxygen, how many moles of sulfur trioxide you’d get. Wouldn’t it be 1.5?</p>

<p>do u remember the question for that one</p>

<p>i looked pretty straightforward to me. 760 is total pressure, just use partial pressures formula. P1 + P2 = P total. 80 percent of Nitrogen and 20% of oxygen i think? so just .8(760)? That came out to be 608, but it said the pressure is around 608, so i just put 610</p>

<p>I got 610 and C2O3. :)</p>

<p>o yea ur right on that my bad, i think it was another Q, like where u half it instead of doubling it</p>

<p>yea 1.5 mol, thats what i got</p>

<p>so was it the extranuclear electrons or atoms are indesctructable for the atomic theory one. i put extranuclear, not sure tho</p>

<p>**** ppl rememebr the T/F Q's i think we need to go over hose, cuz thats wut i usually **** up on?, i have ik 10 wrong so far,</p>

<p>are you gonna get the booklet when they send your score report back?</p>

<p>T/T/CE for Neon one
F/T for water electrolyte
is H2S polar?? i think i put T/F for that one</p>

<p>extranuclear electrons exist in the form of BETA particles...</p>

<p>"atoms are indestructable" BECAUSE fission...Hiroshima...</p>

<p>also, extranuclear electrons could also mean that electrons exist outside of the nucleus, which is obviously true...(electron clouds, orbitals)</p>

<p>wait so what was the atomic theory answer?</p>

<p>yea it is polar i think, but now not sure</p>
