<p>higher BP means more heat required to break IMFs
higher MP = something melts at 20 degree Celsius (for example) so it has weak IMF .. if that made sense</p>
<p>agree with Walton, all the other answer choices were transition metals and they don't react more readily with water than 1A metals.</p>
<p>Walton, I don't think Rb was a choice .. all the choses started with the letter C.
I got last 3 right, princeton, i skipped the first, not sure about 2nd.</p>
<p>Yes to Walton - Rb is crazy reactive
And I think I agree with all of your answers princeton (though I don't remember acid rain in T/F/CE)</p>
<p>oops, nvm I'm talking abt a diff question (for the C's)</p>
<p>i put 1.0 x 10^3 for the reverse reaction (the forward was 1.0 x 10^3)...think i may have missed it (exponent becomes negative?)</p>
<p>reverse rxn was 1.0x10^-3 .. need to take inverse of reg. equilib const</p>
<p>Ya Sapience, you just flip the Keq so it becomes negative (the exponent)</p>
<p>i meant cs</p>
<p>Oh, I found support for the oxidation answer (Woot!!!!):</p>
<p>"oxidation of carbon to yield carbon dioxide" as an example of oxidation in wikipedia's section on redox (okay, it's not the most reliable source, but WHATEVER!)</p>

<p>If you have something that melts at 0 Celsius and something else that melts at 20 Celsius, the thing that melts at 20 Celsius has a higher melting point, and it's intermolecular forces are stronger because it requires more heat for it to melt.</p>
<p>think i missed 5-10 on the test, is that still 700+?</p>
<p>Walton: Cs was the answer for another problem...I'm like 100% it was Rb for the other one</p>
<p>ugh, def. missed 5, got at LEAST 2 wrong now ..so much for an 800</p>
<p>Ya...thats what I thought shravas.
Though what we're discussing here is sort of irrelevant since I believe it asked BP anyway.</p>
<p>And princeton, in addition to your support of oxidation, it can't be sublimation because sublimation is defined as purely a physical change, from solid --> gas. Carbon is not the same as carbon dioxide, so its undergoing a chemical reaction to achieve its gaseous state.</p>
<p>was one of the answers 65 g Zn prod? there was 1.02 x 10^24 atoms Ag+ .. i think it was the first question after the T/F set.</p>
<p>Cs was answer for lowest ionization energy I think.
F- has the smallest ionic radii.
It was 65 g of Zn, since number of atoms was exactly 2 mol...then convert with molar ratio to 1 mol Zn.</p>
<p>^^ Yup! I was just trying to find additional proof to compound the obvious difficulty of calling it sublimination when it's not a phase change. Yes i got 65g Zn.</p>
<p>Sapience - according to Princeton Review, I think you can miss like 20 and still get a 700.</p>
<p>C>CO2 is an ox redox. yes...0 wrng so far</p>
<p>wat was the answer ot the one element that occurs naturally. i skipped thst. also i got 4 ttce</p>
<p>and yeah Zn was 65g i remeber</p>
