<p>Agree with both Echelon</p>
<p>element that DIDN'T occur naturally was one of the 1A or 2A metals, I forget which...</p>
<p>I'm no wrong either and no skip and yes 4 ttce</p>
<p>Sodium never occurs naturally, its way too reactive.
I was deciding between that and sulfur, only because I remembered sulfur came in S8 molecules...but I'm pretty sure its sodium.</p>
<p>EDIT:
Density of gas isn't changed when temperature increases (since volume was constant)
One of the ideal gas problems ended up with a final volume = initial volume of gas (8 L?)</p>
<p>I was surprised to find no electrochem and little acid/base + solubility on the test...</p>
<p>it was sodium</p>
<p>NOOOOOOOOI SHOULD HAVE PUT NA I WAS THINKING OF DOING IT BUT THEN SKIPPED IT. yeah i knoew it was really reactive</p>
<p>wat about the displacement of water one with I II II was it H2 O2 or HCL</p>
<p>HCl is very soluble in water, so it was just I and II (H2 and O2).</p>
<p>i think i put H2 O2 and not HCl since HCl is polar and will be partially soluble in water</p>
<p>nioce!!!!!!!! but it was HCL gass does that matter?</p>
<p>Nope, hydrogen chloride is still soluble as a gas. Barrons drilled that into my head lol.
Does anyone want to confirm my answers in post #62?</p>
<p>yeah 8 L was correct. i beilieve the question also had 8L in it too xD</p>
<p>um.....Pressure=DRT/MM so i said that did relly on temp...what was the answer to that i put ideal conditions or something</p>
<p>i skipped 2 how many can i get wrong and still get an 800</p>
<p>damnit....i didn't read that question right..i thought pressure was increasing and temp decreasing so i thought it was 2 L....but pressure was decreasing and temp decreasing, so volume was constant.</p>
<p>echelon it was density...ideal conditions deviate with temperature and pressure change...ie gases become less ideal at low temperatures and high pressures (I believe; it's either that or the reverse). And, I think I got 8L, but I'm not 100% sure. Does ne1 remember all the numbers in that problem? I know I used V2 = (P1<em>V1</em>T2)/ (P2*T1)</p>
<p>hmm I was thinking about the "deviate from ideal gas" answer. You might be right CC, I'm not sure. However, with density, since the volume doesnt change, and the amount of gas doesnt change, shouldnt it still be the same g/L?</p>
<p>EDIT: I know for sure ideal conditions will deviate with pressure/volume change...idk lol</p>
<p>most active thread xD</p>
<p>Echelon READ MY POST...CC is wrong</p>
<p>EDIT: Oh btw, volume was held constant in that problem. Since D is simply = m/V and V is constant and "m" must be constant, density was constant.</p>
<p>what about the true and false about AgCl froms because HCl is a strong acid was it TTCE or just TT</p>
<p>haha ok thanks princeton. any other questions you all can remember?</p>
<p>EDIT: CC - I think it was just TT there, since it being a strong acid doesn't really affect whether AgCl is insoluble (which it is)</p>
<p>Yeah Thats What I Put But I Was Afraid That Since It Was A Strong Acid It Fored Ions And If It Were Weak The Rxn Wouldnt Take Place</p>
<p>i think that was T T , AgCl precipitates because of solubility rules, not the because of the strength of HCl as an acid</p>
<p>im so glad there was ONE lab question and 0 color/flame test ones and only 1 tritration question (whose answer was something like ph=1?)</p>
