<p>For people that have taken the SAT Chemistry test, what formulas, conversion factors, and constants should I memorize for the test? I'm working through the Barron's book, and it is suggesting that I memorize stuff I didn't even have to memorize for the AP test.</p>
<p>Thanks!</p>
<p>i’ll bump this… i’m curious as well</p>
<p>I wouldnt get too worried.I worked through PR and then Barrons.Although i know a lot more chemistry than either contained i did noticethat barrons has a LOT of extra information that isnt needed for the test(useless info mind u).The chem sub test tests us on our basics and concepts.Barrons tests couldnt even be called reliable because I found them different from the official.Check out sparknotes.
For formulae again you should know the basics(like how to get equilibrium const,etc{VERY IMP…i see a ques on this in almost every practise test}).
Well for conversion factors,i use a list at the back of PR…i found it enough.</p>
<p>I’ve seen most of the important stuff so often in AP that it’s pretty much second-nature now. What worried me a lot was Barron’s calorimetry section; a lot of those numbers (like heat of fusion, heat of vaporization, specific heat) I haven’t used often enough to know off of the top of my head. Do these problems show up often on the real test?</p>
<p>I’m not sure but I think most of the constants are given with the problem (stuff like delta H, reduction potentials…) so you only have to know how to use them. However, I believe other constants like mole, specific heat of water (1 cal/gC?) they expect you to know. Again I’m not sure so don’t take my word for it, maybe somebody can clear it up.</p>
<p>you should know basic things like specific heat of H2O(1cal per gram) i always get sp heat questions wrong :(.
Oh and yes you should know ‘what’ heat of vaporisation/fusion are…or atleast you should be able to use them in stoichiometry.
eg. they might ask a ques on -if the heat of vap of one mole of such and such substance is x.Then what is heat of vap of 2 moles and such.(here you just divide x by 2)
You need not memorise values of delta H…they will be given in the ques.</p>
<p>@Freshman-??mole is not a constant. :S
Dyu mean molec mass? you neednt memorise that as you are given a periodic table with your test…you can refer to that.</p>
<p>Ahh but it is ;p…I meant the definition of one mole of something: 1 mole = 6.02 x 10^23 sorry, should have been more specific</p>
<p>^He might be referring to Avogadro’s number.</p>
