<p>Do you guys remember what the 1 nuclear question was? I remember thinking it was easy, but i kinda forgot what it was/what i put…so now i think i may have read it wrong.</p>
<p>I think the nuclear question was like:
What is true about electrons
I. Electrons are transferred when Mg is oxidized (not sure if this was I)
II. Electrons are released when substances go through decay.
III. Electrons account for 1/3 of the atomic weight.</p>
<p>Answer was I and II.</p>
<p>Which one has the highest melting point.
A. CsF
B. CsCl
C. CsBr
D. CsI
E. CsAt</p>
<p>Bleh, I think I missed this. The answer I think would be CsF, because it has the smallest radius and thus harder to break. I put that originally but then I changed it without thinking to CsAt thinking that because it had the most electrons, it had the strongest LD forces…</p>
<p>What was the answer to
T/F HCl + AgNO3 forms AgCl
T/F HCl is a strong acid
CE</p>
<p>I put T, T, CE, because being a strong acid allows Cl- to completely dissociate from H+ so that it will react with AgCl. Still, I think it may be wrong.</p>
<p>we’re kinda unclear on that one, i put T T, not CE, because the acidity of HCl doesn’t really explain precipitation that well; if it was a weak acid, some AgCl would still form.</p>
<p>i put TT, not CE, and i’m pretty sure it’s right.
although HCl is a strong acid, it doesn’t explain why AgCl forms precipitate</p>
<p>I didnt put CE since I thought that it could have been any soluble Cl- compound and still precipitates.</p>
<p>And dispersion forces don’t affect melting points (?) so CsAt would be wrong, since it has the biggest radius. Also CsF has the most difference in electronegativity</p>

<p>Yah, put T,T for that AgCl question</p>
<p>EDIT: It was a Beta particle decay roman numeral number two in one of the problems.</p>
<p>k, think thanks man; think that’s what i put.</p>
<p>What problem is this? Is that where it said emitted electrons> (Beta decay…)</p>
<p>4 wrong and 1 omitted? That’s just under an 800 right?</p>
<p>yeah, about a 780. I omitted 2 and got 5 wrong which is 770-780. I’m guessing i missed 2-3 more that i haven’t thought of, so i prob got 760</p>

<p>Wait but e- arent released in decay…beta particles are but they arent electrons. Ergo answer is I</p>
<p>^ they can be. there are beta particles as well as electrons released in certain types of radiation. I’m pretty sure at least. on a nuclear quiz for my test there was an electron decay question</p>
<p>[Beta</a> decay - Wikipedia, the free encyclopedia](<a href=“http://en.wikipedia.org/wiki/Beta-Negative_decay]Beta”>Beta decay - Wikipedia)</p>
<p>I don’t know if that verifies it.</p>
<p>nah, sometimes a neutron in the nucleus is decayed into a proton and an electron, an electron being a beta particle</p>
<p>yea, i’m pretty sure it’s I and II</p>
<p>^me too. almost positive.</p>
<p>what do you guys think the curve will be? Same as in the blue book?</p>
<p>^ I think the Blue Book curve is too lenient, because someone mentioned that you can only get 2 wrong for an 800, and I thought this test was pretty easy except for the fact that I ran out of time :/</p>
<p>I’m 98% sure I’m going to cancel, unless 3 wrong (at least) and 3 omit magically passes 780, which I don’t think it will.</p>
<p>that may seem easy, but compare it to world history where 20 wrong is an 800, or physics where 10 wrong is an 800. Chem has the toughest curve…i just hope they don’t make it any tougher</p>
<p>^ Oh I hope you didn’t misunderstand me… I meant that the test itself was easy which means that CB probably gave it a horrible curve (like -1 or -2 equals 800) compared to the BB curve which looked very nice.</p>
