<p>Yeah, I put Calcium too. You just have to remember that transitional metals produce colorful solutions.</p>
<p>@Atomic, for the kinetic molecular theory one, do you remember what answer choice it was? I remember choosing like A. Does anyone remember the other answer choices for that one?</p>
<p>What did you guys get for the one that said a saturated solution had 20g at 100 C and then it’s cooled to 20 C. I thought it would’ve been too easy if we had to just read the graph it gave you so I put 20g because if it’s cooled slowly it would be spersaturated with 20g right?</p>
<p>I think i just subtracted the two amounts lol. Like what it was at 100C - what it was at 20C.</p>
<p>Anyone else do the same?</p>
<p>And what was the answer to Iodine bonding in a network. Was it covalent bonds or london disperion forces?</p>
<p>And what was the molecule that didn’t have the same structure as all the others? I think i put SCl4 or something. It wasn’t SiCl4, i remember putting the one that wasn’t in the same group as the others.</p>
<p>For the iodine one I put London-dispersion because London-dispersion forces are very weak so I didn’t think they would ever be responsible for a full bond, but only for brief polarities. I put covalent as the answer because their electronegativity difference is 0.</p>
<p>For the molecule that wasn’t tetrahedral I put SCl4 because S has an extra electron pair that would make the shape different than a perfect tetrahedral. Also, all the others were in the same group and sulfur was the odd one out.</p>
<p>@Caveboy:
Yes, the kinetics answer was A.</p>
<p>Iodine crystals are held together by London dispersion forces.

<p>Dang, i had london dispersion and changed it to covalent… lol. Anyone remember any other q’s. I think i got maybe 10 wrong and i skipped 4. What score might that be?</p>
<p>@ xthrillakillax I have the same question… what did people put for the super saturated solution one???</p>
<p>The supersaturated one was definitely 20 grams, because, well it was supersaturated. It wouldnt have lost any solute.</p>
<p>hmm… not sure i remember the supersaturated question. Was it the one with the graph of 20g of solute in water in the y axis and temperature in the x axis?</p>
<p>because i don’t remember a question on my test about a supersaturated solution… unless i didn’t completely read the question</p>
<p>Youre correct. It is that question. It never said the word supersaturated, but the answer described it. However much solute went in at 100 C stayed in when cooled to 20 C.</p>
<p>the supersaturated one with the graph, I’m pretty sure you were just supposed to subtract 5 from 20 so 15.</p>
<p>What did you guys get for the matching one where it asked, which of these particles passes through a conductive aqueous solution or something like that.</p>
<p>I think you’re referencing this:
Anions carry the negative charge in a conductive aqueous solution.</p>
<p>Yes, I put anions for that.
Wait so, for the saturated graph one, is the answer 20g or 5g?</p>
<p>I think you were supposed to subract the two amounts, so 20-15= 5.</p>
<p>Where are you getting 15g? Was that the solubility at 20 C?</p>
