<p>What do I need to memorize? I memorized the basic period table trends, some simple solubility rules, the PV=nRT gas law, LeChatelier's principle, and some things about acids and bases.</p>
<p>My main concern is if (since I don't actually have a real Collegeboard Chem test) they give a compound and I don't know that certain ion, such as, acetate, or Hydrogen Sulfate. So for anyone who has a real collegeboard chem test or who has actually taken the test, do you have to memorize ions? Or do they give the compound or ion to you in parenthesis at the end of the question?</p>
<p>Also if you have taken the test or have a real test, please tell me if there is more that I should memorize before the test.</p>
<p>Any help at all would be appreciated. Thanks.</p>
