Any advice on chemistry??

<p>i got a <em>cough</em> 490 <em>cough</em> on the SAT2 chemistry. Yeah its horrendus. I got an A in Honors Chem., but that didn't matter after all. I had trouble with stuff i never learned especially doing problems without a calculator. HOW CAN YOU DO CHEMISTRY WITHOUT A CALCULATOR, LIKE FOR ACID-BASE DOING ANTI-LOGS????? Well, I guess you can. And that's why I ask your advice on this test. Any other tips would help.</p>

<p>Thanks</p>

<p>That's one reason why I didn't take Chemistry SAT II because i'm not very good at simple calculations. I'm slow at it. Probably from lack of practice. Try to take another SAT II that doesn't require any computations.</p>

<p>"I had trouble with stuff i never learned ..."</p>

<p>Buy a prep book and do all the practice in the book. </p>

<p>Your score should/will rise dramatically.</p>

<p>Just a word of caution, if you're looking to do a science SATII, most people find biology to be an easier course, but there's A LOT of stuff that's not on the curriculum on the SATII.</p>

<p>I think you will do fine. I do not have a high SAT score (1280), I never apply myself, I never listened in AP Chemistry, but I got 700 on the subject test and got a 3 on the AP exam. The logarithm questions on the test are basic. You will do fine as long as you remember: x^y=z log.(z)=y (where . is the base of the logarithm, x). That is all I can remember with logs. The only other stuff is just basic stoichiometry. And just so you know!!! I was an idiot when I took the test, for some reason I thought that there were no point deductions for the wrong answer--what can I say?--so by the end of the test I still had a bunch of blanks so I just guessed.</p>

<p>760 on sat ii chemistry baby!!!!!!!! im still in shock..i knew NOTHING AT ALL, and starting the tuesday before the test i bought princeton review book and did 2/3 chapters a night, just reading it and doing all the practice problems. i took the 2 practice tests in the back of the book on friday night, got a 570 and a 600 or something, got *<strong><em>ed, said *</em></strong> it, went to sleep, woke up and got a 760!!! yay me!!</p>

<p>nice!!! see that is the kind of hard work and dedication that I envy!!!! nice job</p>

<p>You should look at princeton review for AP chemistry. That book is really complete and helped me a lot of the SAT II and the AP exam.</p>

<p>I had that book. Then I lost it.</p>

<p>try PR and Kaplan</p>

<p>lol..yea my pr book was from 2001/2002, so i REALLY thought i was screwed...i could have sent u mine if it was a little earlier..what does everyone do with their old books? it doesnt feel right just tossing them</p>

<p>This may be a dumb question, cause i'm not good at math, but when you figure out the pH level you use the log of base ten. What does that mean?</p>

<p>From what I can remember.... not very much.... acids are also measured by concentration...molarity.... concentration of hydrogen proton [H+]
now here is where my memory is a lil sketchy...</p>

<p>umm..yea i dont understand the technicalities behind that, but i always say examples work best:</p>

<p>say if the hydronium concentration is 10^-5, then the pH is 5 so pH = -<a href="i%20think">log H</a></p>

<p>if it says the hydroxide concentration is that much, the POH would be 5, and the PH would be 9 (14-5) does that make sense...? a book would explain it way better</p>

<p>i just found an eqn from last year:
Kw=[H+][OH-]=1.0 * 10^-4
therefore, it is base ten because the concentration of the hydrogen proton is expressed as a power of ten, and like Lisa says, pH=-log[H+] or -log[H3O]
when you take the logarithm(base 10) of the concentration, you cancel out the power of ten and get the POWER OF HYDROGEN!!!!! mwuaahhaha</p>

<p>That was helpful thanx guys.</p>

<p>no problem. I can't believe how much I have forgotten.</p>

<p>wait. so if i study the cliffs AP bio, will i be able to get 700+ on the SAT II?</p>

<p>or do you suggest me reading my PR AP chemistry, and taking the SAT II on that(and getting 700+)? </p>

<p>it doesn't matter which one i take, i just want to take the one which will be best for me, so which test do you think i should take? i am equally skilled(skilled. ha! i dont know another word to use) in both...</p>

<p>so do you think i can get a higher score by reading the PR AP chem book and taking the SAT II
or </p>

<p>reading the Cliffs AP bio book and taking the SAT II</p>

<p>jcas323: "You should look at princeton review for AP chemistry. That book is really complete and helped me a lot of the SAT II and the AP exam."</p>

<p>so are you saying I should get an AP chem. prep book for taking a SAT2 chem. test? I haven't taken AP Chemistry in school either.</p>

<p>do you miss the whole question for the true/false even if u miss only one part of it???</p>
