<p>yea 1/9 was one of the answers</p>
<p>other one, i put zero slope b/c mol to mol ratio was 2:2</p>
<p>1/9 was right....</p>
<p>what was the question w/ zero slope??</p>
<p>o snap!!</p>
<p>i was thinking that, about the slope....dammitt!!!!!</p>
<p>it had something to do with H2 and O2 reacting to give H2O as a product and showed 5 graphs where mols of H2 were compared with O2</p>
<p>And by the way, lets go over cause-effect....</p>
<p>ok, questions?</p>
<p>Mols of H2 were compared to O2? Crap, I read the graphs wrong and compared to H2O. DOH!</p>
<p>And I hardly remember the Cause and Effect ones. Except for that copper one. So Copper doesn't dissolve in hot water? : /</p>
<p>no.. it began increasing then zero-slope..</p>
<p>sorry it was mols of H2 compared with mols of H2O, i accidently put O2 in my post</p>
<p>Yeah, that's what I remember putting. The increasing and then zero slope because O2 runs out eventually or something. It has only been a few hours and already, the questions are slipping O:</p>
<p>o really, i thot the question just said the relationship btw H2 and H2O, i didnt read nething about increasing then zero-slope</p>
<p>Oh it was. It's just that, from what I remember, you had unlimited H2 while O2 was specified. So as you keep adding H2, H20 keeps on forming until you run out of O2. After you run out of O2, the slope hits zero and formation of H20 stops.</p>
<p>but the thing is that, we need not compare the mass, wasnt it only talking about mol relationships, so as many mols of H2 there are, as many mols of H2O we ll have</p>
<p>yes... and for pressure/temperature problem.. it was 22.something right..</p>
<p>cause Gay-Lussac's law.. right??</p>
<p>T1 P1
-- = ---
T2 P2</p>
<p>dammit, i lost my 800 with that question</p>
<p>I remember crossing out A and E imediately on those because they were too extreme. Then I took a guess between B and C, and I think I chose the 22.X one because I was so far behind and time was running out. It just seemed the most reasonable... :O Anybody else verify?</p>
<p>i dont remember that question</p>
<p>What did you put for the Copper Question???</p>
<p>Copper dissolves in water BECAUSE
Copper is very reactive</p>
<p>right???</p>
<p>I think Copper works like this...</p>
<p>Cu + H2O ---> Cu+ + OH- + H2 ---> CuOH + H2</p>
<p>the sig fig question was 2.oo right?</p>
<p>for the thing u guyrs are talking about, is that the one where u had like 47 atm at first. and the temp was 25 or something?</p>
<p>I said T, F</p>
<p>I don't know... I thought copper is reactive but is it VERY reactive? I couldn't be sure : /</p>
<p>tm2000,
I got 3 sig figs so I agree with you there.</p>
<p>And that is the question we are talking about.</p>
