<p>I had a chem test today on solution stoichiometry and solubility and I'm a bit worried about it.</p>
<p>Can you tell me if these answers were correct.</p>
<p>Which of the following produces visible crystals at equilbrium?
A. saturated solution
B. unsaturated solution
C. supersaturated solution
D. all of the above
I put saturated but I'm worried that may be wrong because..well is it all of them?</p>
<p>Which combination does pressure have the greatest effect on?
A. gas-gas
B. solid-liquid
C.gas-liquid
D. liquid-solid
E. solid-solid
I put C because of Henry's Law, but I had no clue</p>
<p>Why is it easier to make a supersaturated solution of ammonium chloride than it is of sodium chloride?
I put something about how you need higher temperatures to make sodium chloride supersaturated and that you need more solute. I BSed it, is that correct?</p>
<p>And the calculations...god I worry so much I made a miscalculations...can't wait for monday.</p>
<p>I think they look right, but I haven't taken AP chem yet. Also, I hate to be the bearer of bad news...but are you sure you have class monday? Pretty sure it's a national holiday Monday.</p>
<p>no school monday for me :p
i think that the first one is supersaturated soln b/c if it were in equilibrium (it's not when it is supersaturated) then crystals would appear (i know its not unsaturated, thus it is not all of the above, so A or C, 50-50 shot!)</p>
<p>im pretty sure that pressure would have the greatest effect on solid-solid because solids are much less compressible than gases/liquids</p>
<p>oh jeez
i do have school monday
we had a snow day and our school doesn't have built in days
so we have to go on mlk day and presidents day it sucks
btw..this isnt ap chem
just honors, ap i may have next year.
oh the anticipation of this test lol...i hope i can keep my 100 average but im so worried</p>
<p>Don't feel too bad, we have school monday too... we don't get the friday before labor day off either... or president's day... we have tons of days we don't get off... and it's not even because we have days we missed.</p>
<p>We started... august 25 i think, same as most other schools, and we get out i think the second week of june... we have a longer winter break, though, and we do have a few days off that no one else does... but we don't have a midwinter break, either... i dunno, it's weird.</p>
<p>So you have a longer winter break. Well, doesn't that pretty much even it out? I don't have a midwinter break. I only get a Monday off during the entire Presidents' Week.</p>
