<p>Ask as many questions as you can!!</p>
<p>How do you tell if something is london or dipole force or polar without drawing the lewis structure?</p>

<p>For question 1b, can you say that equilibrium favors reactant instead of saying from right to left?</p>
<p>^ yup, you can~</p>
<p>I just find writing those equations so hard on the FRQ…anyway to study for those?</p>
<p>iamsocool,
my teacher has a book of nothing but net ionic equations. I borrowed it and am just going to do a lot until I get it. basically solubility though.</p>
<p>anyone know how many right you need to get on multiple choice and free response to get a 5? can’t seem to find any score calculators</p>
<p>Teacher told us around 70% correct for a 5, provided you do about the same on frq.</p>
<p>Really? My teacher, and several books I’ve looked at said the required percentage is a 55% overall on the exam.</p>
<p>70% is a bit too high; I don’t think any exam except for AP Gov has a 5 range that high.</p>
<p>Really? My teacher also told me 70% + is a 5.</p>
<p>Hm…well that’s pretty tough.</p>
<p>i think 55% is way too low for a 5…maybe 55% to pass with a 3?</p>
<p>so to guarantee a 5 aim for ~80% on practices?</p>
<p>also i’m unsure about how they look at significant figures in frq. does it have to be correct number of sf or you don’t get any credit?</p>
<p>can someone give me a quick list of solubility rules? I haven’t memorized these yet. <em>gasp!</em></p>
<p>to answer my own question…</p>
<pre><code> 1. All common compounds of Group I and ammonium ions are soluble.
-
All nitrates, acetates, and chlorates are soluble.
-
All binary compounds of the halogens (other than F) with metals are soluble, except those of Ag, Hg(I), and Pb. Pb halides are soluble in hot water.)
-
All sulfates are soluble, except those of barium, strontium, calcium, lead, silver, and mercury (I). The latter three are slightly soluble.
-
Except for rule 1, carbonates, hydroxides, oxides, silicates, and phosphates are insoluble.
-
Sulfides are insoluble except for calcium, barium, strontium, magnesium, sodium, potassium, and ammonium.

<p>It’s okay, I haven’t either, I only remember the basic ones and the ones about acid/bases lol.</p>
<p>i pulled it out from PR</p>
<p>Cations</p>
<p>Alkali Metals are all soluble
Ammonium salts are soluble
Alkaline Earths/Transitions metals are sometimes soluble</p>
<p>Anions</p>
<p>Nitrate salts are soluble NO3
Chlorate saltes are soluble CIO3
Perchlorate salts are soluble CIO4
Acetate C2H3O2 are soluble
Chloride, Bromide, and Iodide salts are soluble except for Ag, Pb and Hg
Sufate salts are soluble except for Ag, Pb, Hg, Ca, Sr, and Ba</p>
<p>Hydroxide salts are insoluble except those contain alkali metals which are soluble</p>
<p>Carbonate salts are soluble except those contain alkali metals and ammonium</p>
<p>Phosphate salts are insoluble except those contain alkali metals and ammonium</p>
<p>Sulfite salts are insoluble except those contain alkali metals and ammonium</p>
<p>Chromate salts are insoluble except those contain alkali metals and ammonium</p>
<p>Sulfide salts are insoluble except those contain alkali metals and ammonium</p>
<p>thanks lemone!</p>
<p>Anyone have a list of transition metals with their colors?</p>
<p>Like when it asks you what ions turn what color and crap no one knows about?</p>
<p>I’ll be doing some hardcore studying this weekend.</p>
<p>
</p>
<p>And Cu+1 right? </p>
<p>I always forget what the lower 2/3rds upper 1/2 stuff is. I think that’s what I will memorize the night before.</p>
<p>I’m ****ting myself about this right now.</p>
<p>Im using the Princeton Review for AP Chem right now ^_^</p>
