<p>500th post! yeeeeeeeea lol
well even though it said “physical properties”, Mendeleev predicted the density of Ga, so that was T T CE right?
and arghh. i made that mistake too with the question of 14.7, i put 1.47 because i thought .5 *.2 = .01 as well
urgh. so far so good tho, only 2 wrong, 0 omitted</p>
<p>Yeaaah. :\ I had the same issue about N2 and CO2, but I just put CO2 in the end.</p>
<p>noooooo fail 501. =_= so close!!</p>
<p>And I am absolutely positive that part II of the Mendeleev question stated same total electrons. So it was T/F. I read that question at least three times to make sure I wasn’t misreading, haha.</p>
<p>What did you guys get for the ionic radius problem? I blanked out on the trends, so I had to kind of reason my way through the problem. I recall putting something like Mg2+. Was that a choice?</p>
<p>for the question about the h2o produced, was that 11.2 L? i didn’t think so because it said at stp, and h2o is liquid at stp right…?</p>
<p>for N2 I think the main problem is that there wasn’t a proper angle - if you think about math classes, they always ask for an angle as “angle A B C”, and you look at B to find your angle.
However for N2, you only have two atoms, so there’s no angle being formed.</p>
<p>@ Anrajg ; Yeah, I thinnnk that’s what I put.</p>
<p>@ Chingstah ; I don’t think I marked that because of what you said about liquid @ STP. :]</p>
<p>i think mg +2 was right
more protons in the nucleus pulls in the electrons more?</p>
<p>Yeah 10 char</p>
<p>oh ok haha i kept reading people saying it was 11.2 so i was getting worried xD</p>
<p>Mg 2+ because less electrons with more protons create a greater pull due to the nucleus’ attraction to the electrons, making the ionic radius smaller.</p>
<p>Will someone repeat the 14.7 question?</p>
<p>no its was BECAUSE it has the same number of ELECTRONS as aluminum and therefore its FALSE</p>
<p>We know now ihs</p>
<p>Solid on the ionic radius trend. I guess my reasoning worked. I’m pretty sad about the Mendeleev question though. This is my first time taking a subject test. Do you guys think they will curve questions like that or are “trick” questions (I know they aren’t necessarily trick questions, but I don’t seem to be the only one who read it too quickly) to be expected on tests like these?</p>
<p>I don’t know what the raw scoring is. On Sparknotes and Barron and McGraw, it says like skip 6 or 7 and it’s still and 800 but some people are saying it’s miss 2 and it turns into a 790 so… I’m confused.</p>
<p>so what was the answer?</p>
<p>that’s what I thought…
but i don’t know what i put for the devation question.</p>
<p>Mendeleev - T, F?</p>
<p>I remember seeing the word “valence” in the question, but the overwhelming consensus is that it is T, F. I’m not sure what it actually was.</p>
