<p>the dissociation of HCl allowing flow of electricity i think</p>
<p>did you guys get, positive oxidation state:lead
yellow green gas with choking smell: chlorine
yelow that melts above h20 temp: sulfer
and then lead for the other one</p>
<p>that was T, T, CE…did anyone get a lot of F, T? And does anyone remember the other CE’s?</p>
<p>filter paper was for imiscible liquid and percipitates?</p>
<p>@ chemaster – yep i got that exactly i think! (i had lead for 2 – was kind of fishy but i went with it)</p>
<p>and yeah sccr i got quite a few false trues (i think one had two in a row?)</p>
<p>umm i just said to separate precipitate…</p>
<p>i got like three or four FT’s in a row</p>
<p>i remember a lot of F T. for filter paper i put precipitates cause filtration solids v. liquids only.</p>
<p>zinc was more electronegative/ it did have double the electrons but not ce
right?</p>
<p>@chemaster: I put T T on that one too. I don’t think it’s CE because zinc is a metal and metals have a sea of electrons, causing it to be a good conductor of electricity. I don’t recall the answer talking about electronegativity though…</p>
<p>oh yeah, conductivity, my bad</p>
<p>what about some of the other i ii and iii questions</p>
<p>Dang… I forgot. I’m a bit worried now since I only had 3 CEs…</p>
<p>Thought that was pretty easy… </p>
<p>Only skipped two, and the rest I’m pretty sure are correct. Hopefully there’s still a curve, because I just need to know that there’s always room for silly mistakes :P</p>
<p>oh yeah the quartz crystalo one
i know iii was wrong (opposite of le chatier)
i think i put solution was saturated, other choice was stirring would dissolve it completely</p>
<p>Yep, I put the same thing.</p>
<p>i put saturated and cooling would cause a precipitate</p>
<p>didnt it say cooling would disolve it?</p>
<p>crystallization which means the solution had to be supersaturated. I wrong. if you cool supersaturated, nothing happens… heat supersaturated leads to more of the solute dissolving so III was wrong. cooling didnt do anything. II was stirring leads to more dissolvin’ and it’s last option.</p>
<p>Harvard76, that’s what I put too.</p>
<p>well it said after it reaches equilbrium. if its at equilbrium stirring it will not do anything cause no more can dissolve aka. rate of dissolving equals rate of crystillization. saturated solutions are at equilibrium and if you think of your solution chart when you cool something it will go above the point of saturation.</p>
