<p>Does the SAT Chemistry test have Ksp and all that common ion effect stuff, like actual problems?</p>
<p>I would really appreciate an answer because I don’t want to waste studying something that isn’t covered.</p>
<p>The math wasn’t that bad at all. I found some of kaplan’s math questions harder, and even then there was only one question I did not really know how to do. However, according to most other people, the math on barrons isn’t even close to the level of math needed for the actual test.</p>
<p>What are anhydrides (basic and acid) and hydrides?</p>
<p>acid anhydrides form acids when put into water (nonmetals)
basic anhydrides form bases when put into water (metals)</p>
<p>hydrides are compounds with hydrogen like a metal hydride=metal +hydrogen</p>
<p>Do we have to know all of the chemical constants, specifically:</p>
<p>Kf = 1.86
Kb = 0.512
8.31
0.0821
F = 96500
h = 6.63E-34
specific heat, heat of vap, heat of fus for H2O
etc.?</p>
<p>^i think the first four are really the only ones you should bother knowing</p>
<p>really?
but they have to make computations easy, right? 1.86 and 0.512 don’t seem very nice numbers to compute with.</p>
<p>yes… example:</p>
<p>100g of compound X (molar mass 50g/mol) is dissolved in 2000g of water. what is the new freezing point? or what is the new boiling point?</p>
<p>does anyone think that test 4 in the barrons book was really easy? I did it in 40 min and only missed 2… I hope the real test goes this way</p>
<p>Do we have to know the flame test colors and the indicator colors? I’m pretty sure we have to know the flame test colors, but i’ve only seen the indicator colors in the McGraw Hill book. (i.e. colors of litmus, phenolphthalein, methyl orange, etc. in base/acid)</p>
<p>doubt cb will ask u colors… most they will ask u is which turns litmus paper blue? then they list 4 non-basic substances and 1 basic one… woohoo</p>
<p>indicator colors are easy if you’ve already taken ap chem… but if you don’t know them i think it would be a good idea to memorize them</p>
<p>litmus turns blue in base because both start with b, and methy orage turns from red to yellow from acid to base which makes orange…</p>
<p>i took ap chem and dont know **** about indicator colors</p>
<p>haha
here’s a list of out-of-the-blue (not typical) topics i’ve seen in practice tests.</p>
<p>SHOULD WE KNOW…</p>
<p>The third most abundant gas in the atmosphere
Adding water to a buffer does not change the pH!
delta G = -nFE
On earth, most helium is created by alpha decay.
In the universe, most helium is created by nuclear fusion.
Compounds are colored for two reasons: they are organic molecules that have conjugation, or they have transition metal atoms.
Over 99.99% of oxygen in the bloodstream is found as H2O.
Coulomb’s law: F = Kq1q2/r^2
Catalysts cannot make nonspontaneous reactions occur.
Memorized activity series?
deliquescence!
The anatomy of a nuclear reactor. (??? what the…)
a catalyst can slow down OR speed up a reaction.
Homologous series…
Aromatic compounds…
Nernst equation</p>
<p>The third most abundant gas in the atmosphere…is argon…right?</p>
<p>deliquescence… something dry becomes wet in normal atmosphere conditions</p>
<p>anatomy of a nuclear reactor… hope this isn’t on there because I have no idea</p>
<p>catalyst can slow down OR speed up a reaction… what? I thought it only speeds up by lowering the activiation energy or helping the reaction proceed…</p>
<p>aromatic compounds… ethers, rings</p>
<p>I just got a 750 on SparkNotes. Someone please tell me it’s harder.</p>
<p>its suppose to be harder… but also there are alot of errors which messes up your score</p>
<p>buzzer11. i know almost none of that list. saw none on the ap exam and saw none in cb practice tests… lol</p>
<p>Yeah I just went back through and looked at everything and everything I got wrong was either SparkNotes’s fault or simple mistakes. Is that a good sign?</p>
<p>
I’m pretty sure you don’t have to memorize any of those. PR says they give you the gas constant, and there’s not a whole lot of formulas/constants harder to memorize than that.</p>
