<p>I still don't get why the KCL solution is not supersaturated... Can anyone explain it for me?</p>

<p>fck you @ssh0le</p>

<p>^LOL. That seriously made me laugh</p>

<p>And btw read your own wiki link...
linear = x-A-x
scroll down a bit and..
AX1En Diatomic (nothing about linear) until u go down to a 3 atom molecule.
You guys have an idea stuck in your head, and refuse to believe the truth. Like i said you cant make an angle with a single line. Instead of dissing me try thinking a bit</p>

<p>Edit: Even more, a diatomic molecule has no central atom as you hopefully shud know...</p>

<p>koken911 i dont know what u r trying to prove. A molecule with only with only 2 atoms is linear and has no angle. Thus, all diatomic molecules are linear and they are nonpolar.</p>

<p>Wikipedia>Textbook I get it now...</p>

<p>Does anyone remember any more questions?</p>

<p>rjacob: I am saying that yes they are nonpolar, but no they are not linear; READ THE WIKI POST THAT YOU GUYS PUT UP
VSEPR</a> theory - Wikipedia, the free encyclopedia
Seriously this time read it before you post...look for diatomic and notice how it doesnt say linear next to it and it defines linear as x-A-x, while diatomics are x-x
LURK MOAR!</p>

<p>You guys are blatantly ignoring the truth. You give me a wikipedia link and i just show you how it agrees with me. Im out of here sorry for disturbing your ignorance</p>

<p>Koken911, actually u r wrong. ALL diatomic molecules and ALL 2 atom molecules are linear; look at this and search ''diatomic'' in the page. Molecular</a> Models & VSEPR Theory</p>

<p>haha look at this </p>

<p>quote: "A diatomic molecule, a molecule composed of only 2 atoms, must always be linear in shape as the centers of the 2 atoms will always be in a straight line"</p>

<ol>
<li>What was the exact question about the linear, diatomic, nonpolar molecule? My mind is blank. </li>
<li>Isn't Increasing Ionic character N2<FCl<KO?</li>
<li>The KCl question was about a saturated solution, I think, not supersaturated. So it wouldn't crystallize when you seed it? I'm not sure about this and I'm doubting my logic on this one.
(Just an observer)</li>
</ol>

<p>It said all diatomic molecules are nonpolar BECAUSE they are all linear</p>

<p>TT</p>

<p>and N2<FCl<KO is Correct</p>

<p>the 3rd one i skipped.</p>

<p>So no one has a conclusive answer on the KCL solution question?</p>

<p>what about one of the last ones with pressure and temperature</p>

<p>sorry forgot the exact question</p>

<p>i think i just put the lower temp/higher temp, lower press/higher press (probably wrong, but i just guessed on that one...i could narrow it down a little)</p>

<p>I only put I. Saturated solution because I'm pretty sure the other answers said that ALL the solute will crystallize with the change in temperature.</p>

<p>well after every test people do it</p>

<p>although im pretty sure it is prohibitted</p>

<p>ya what about that pressure/temp on. Where it said something about gases being more Ideal? It said High pressure low pressure.. or something.. i</p>

<p>ideal conditions are low pressure and high temperature. i think the answer had something to do with high pressure</p>

<p>i forgot the question, but gases are ideal at high temps and low press. When they are under high press and low temp. they donr act as ideal gases because of intermolecular foreces.</p>

<p>Do all diatomic molecules necessarily have to be of the same element?
The general consensus on this thread seems to be yes.</p>

<p>But...
Googling the question gave me both possibilities, yes and no. If they were composed of the same element, their linear structure (Net pull of zero) would explain why diatomics are nonpolar so the answer would be be TTCE, wouldn't it? Otherwise it would be FT since not all diatomics are nonpolar (if you consider HCl and HF diatomic).</p>
