<p>Vestige yes it is. Thats why it was FF</p>
<p>haha yeah i misread that ;p</p>
<p>btw, there were 70 MC on my test, only 15 T and F questions</p>
<p>i had -4 on mine last month (in may) and got a 790. just for references on the curve.</p>
<p>dang, that is harsh</p>
<p>yeah i was angry(want to major in chem), but then realized that i did better than 95% of the nation..... and better than 2% of college confidential (JK LOL)</p>
<p>what was the answer to the question for the one that said "Which one is least likely to be a Bronsted-Lowrey Acid?"</p>
<p>if i remembered the choices correctly the answer is CCl4</p>
<p>"Diatomic molecules are molecules made only of two atoms, of either the same or different chemical elements. The prefix di- means two in Greek." So says Wikipedia</p>
<p>So ppod is right.</p>
<p>and BF3 is trigonal planar. it can does not follow the octet rule. It is in the third column IIIA</p>
<p>Yet in addition to that it also says "Diatomic molecules in forms of X2" </p>
<p>Funny how all of us tend to forget parts of the question after the test.</p>
<p>teenage said the following
//Ugh, totally missed the 2+ with the Mg.</p>
<p>The diatomic-polar thing was definitely TT, not CE because I remember part i of that question reading "A diatomic molecule in the pattern of X2".</p>
<p>I also got two Pb, I think the first and the last, for the classification.//</p>
<p>ya so lets make a list of the MC, we alrdy have 1 for the true and false.</p>
<p>okay</p>
<p>-Nitrogen (n2) - Triple Bond
-1P205 + 3H20 ---> 2H3PO4
-Least Likely Electrolyte- CCl4?
-Moles of H2 and some other gas-- 0.5 Moles
-M3N, Unkown Metal Question- 7.0 grams
-Some Balancing Coefficients for H20- 9
-Least To greatest of something N2<?<?
-Equillibirum Expression
-Mg+2 Electron Configuration- 1s2, 2s2, 2p6
-Using a filter question--only to separate from a precipitate
-Type of Bond in a Diamond- Covalent Network</p>
<p>People can add to this list :)</p>
<p>yellow-greenish gas? - chlorine
most likely to conduct electricity metal? - Pb
most oxidizable? - Pb
yellow solid - sulfer
used to see a precipitate reaction - test tubes
used to measure volumes - volumetric pipet
used for titrations - burette
drawing of forward uncatalyzed reaction - E(?)
drawing of forward catalyzed reaction - C(?)</p>

-Accuracy Problem- A, + or - 0.2?</p>
<p>thought of one^^</p>
<p>Didn't it ask for the REVERSE uncatilized reaction?</p>
<p>Add H+ atom to make it acidic
CO3 2- is a base(conjugate)
0.67mol of NH3 for the last problem
N2>FCl>KO
3.0 for the density
valence electrons and oxidation number, for the one that asks u about the elec. config. It was a roman numeral question. I and III
Volumetirc flask for the NaCl solution.</p>

Oxidation State (Number) of a Certain Compound-forgot
The only nuclear chemistry one- Beta! (convert neutron to proton)
shape of BF3 - Trigonal Planar (3 shared, 0 unshared)</p>
<p>CO3 2- is a base(conjugate)</p>
<p>Can you elaborate on that?</p>
<p>yep so the question was HCO3 + H20 -> CO32- + H30
so on the left, u have a strong acid HCO3, and on the right side is an acid H30, CO3 is simply the conjugate base of the HCO3 on the left side. If you take the H off, u get CO3. yep idk if thats a good explanation.</p>
<p>anyone have any idea what a 10omit and 7wrong would equal? PR says its 740.</p>
<p>I heard from my friend that the curve is -8. Is it true?</p>
