<p>hmm weird
it says 25th on the main page but 23 here

<p>im not excited to get my score...unless its around 800</p>
<p>the second part of the Gallium question is false-- Ga and Al do not have the same TOTAL number of electrons, but they have the same number of valence electrons</p>
<p>For the X2O3 one -- they probably did expect us to know that Boron doesn't follow the octet rule and is most stable with 4 valence electrons. -__- So we could, like, add together the valence electrons (3<em>2 + 3</em>6) and get 24 and like... draw a picture or something lol. Not that I have any idea what a molecule of that would look like. </p>
<p>Yayyy another one I got wrong. ~__~</p>
<p>Boron doesn't act like aluminum because aluminum is a metal and boron is not. Aluminum forms Al2O3 by bonding ionically. Boron bonds covalently. If you tried to draw a covalently bonded boron oxide molecule you'd see that boron would only be able to make discrete molecules of B2O2. B2O3 is something different, similar to a network covalent structure like SiO2. I guess we can't really tell whether they'd ask you about something like that.</p>
<p>Scratch that. Technically you can get a B2O3 molecule by putting a central oxygen 2 borons single bonded off it and a double bonded oxygen to each. I'm still not sure if that's what they were looking for though.</p>
<p>For I2 (iodine) was that london dispersion forces?
Also for one of the early sets, was the first answer decomposition?</p>
<p>What was the question for the iodine?</p>
<p>Also, I'm kind of nervous about what I might have gotten and whether I should cancel. I know that I left out 3 questions and I probably got like 4 wrong, maybe a little more. What approximate score would that be? Cuz I'm aiming for high 700s...any chance?</p>
<p>I2 is a covalent bond.</p>
<p>thats prolly like a 770ish id wanna say.</p>
<p>and X2O3 was Fe and B, darn it. Even though B2O3 shouldnt form cuz B is weird, it still exists, and the question just asked which ones would form, and didnt have any specifications.</p>
<p>Thanks :-)</p>
<p>And was that X2O3 question a TTCE? or a multiple choice with "B and Fe" as one of the answer choices? I somehow remember putting B and Fe.</p>
<p>yeah the Iodine question wanted the intramolecular force (not the intermolecular) because I remembered it was a tricky question
London Dispersion is intermolecular and covalent is intramolecular; I put whatever it asked for, which was intramolecular covalent</p>
<p>What was the Hess' law question?</p>
<p>^ the one with the graph of Delta H triangle.</p>
<p>Was the answer DeltaH1= DeltaH2+DeltaH3??</p>
<p>^^^ Yes i think it was H1 = H2 + H3</p>
<p>how many TTCE were there?</p>
<p>Did the iodine question say I2(g) or I2(l)?</p>
<p>If it was liquid iodine, then I would think the answer was london dispersion...but it probably was iodine gas so in that case the answer is covalent.</p>
<p>I seriously cant remember what i put...crap.</p>
<p>I had around 5-7 TTCEs.
I got a lot of them in a row near the end of the TF section.</p>
<p>I think it was gas but would that matter? They wanted to know the INTRAMOLECULAR force, not the INTERMOLECULAR force. London Dispersion is intermolecular.</p>
<p>if they specifically said intra- forces then it wouldnt matter
but i remember them just saying forces...</p>
<p>agreed with TheMan66, a small trap by CB :)</p>
<p>baaaaaaalllllliiiiiinnnnn</p>
