<p>ok so from the other thread, i combined my list with others to make a big list of many questions. Lets keep it specifically to questions that appeared on the test, and not create side conversations. here it goes</p>

<p>-Nitrogen (n2) - Triple Bond
-1P205 + 3H20 —> 2H3PO4
-Least Likely bronsted lowry- 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
-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(?)
-which one of the processes is sublimation? - the one with S->g states
-finding density through water displacement - 3.0
-Vaporization of something (80degrees and 200sth) - 4400
-KCl question - Saturated
-Gases being ideal (when we are at high pressure) - answer is high temperature low pressure
-Moles of NH3 in a reaction N2 and H2 - .67 moles
-Which makes a bronsted lowry base into a bronsted lowry acid - H+
-Temp vs Pressure graph - increasig upward slope line
-Pressure vs Volume graph - curved
-water freezing graph - 1 plateua where temp was constant
-BaSO4 balancing problem - coefficient 1
-BF3 molecule geometry - trigonal planar
-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.
-CO3 2- is a base(conjugate)
-Accuracy Problem- A, + or - 0.2 </p>

<p>Oxidation State (Number) of a Certain Compound-anyone remember the comp?
The only nuclear chemistry one- Beta! (convert neutron to proton)</p>

3

<p>yes
the nuclear was beta, the oxidation number was like H2CrO7 or sth of that sort. it asked for Cr's oxidation state, and it was 12+, i might have messed up the elements but the answer was 12+ i believe.</p>

4

<p>-Temp vs Pressure graph - increasig upward slope line</p>

<p>I don't think there is such question on the test.</p>

<p>No it's 6+. There is a 2 subscript next to Cr.</p>

5

<p>really? i only saw 1 Cr :&lt;/p>

<p>Chromic acid generally refers to a collection of compounds generated by the acidification of solutions containing chromate and dichromate anions or the dissolving of chromium trioxide in sulfuric acid. Often the species are assigned the formulas H2CrO4 and H2Cr2O7. The anhydride of these "chromic acids" is chromium trioxide, also called chromium(VI) oxide; industrially, this compound is sometimes sold as "chromic acid."</p>

<p>Regardless of its exact formula, chromic acid features chromium in an oxidation state of +6 (or VI), often referred to as hexavalent chromium. Chromium can exist in a number of oxidation states, hexavalent state is the highest. In its reactions chromic acid is reduced in redox reactions to the purple [Cr(H2O)6]3+ ion, or other Cr(III) species, which usually have a green colour.</p>

<p>-Temp vs Pressure graph - increasig upward slope line
Are you sure there is such question? I only remember there is Pressure vs Volume.</p>

7

<p>my my my. if I had taken SAT chemistry and i saw the answers you've posted i would have completely flipped out. because i remember i was soo insecure about it last year and wanted to cancel. i can't look at answers when i'm worrying.</p>

8

<p>hmm idk, maybe i misread it because of the fact that i was on question 50 when they called 5 min, i was rushing. Grr.. thats like 8 wrong so far.</p>
