<p>1) In the Zumdahl book, which chapters do I have to know for the exam? (I heard it was the first 17 or so)
You should add Chapter 18 and 19 to that list. I don’t have my book in front of me, but that’s the chapters we just did in my class. 2) Which chapters/units are the most difficult?
I’d say acids and bases were difficult in the beginning. (I can’t make all the chapters…they were sort of spread out). I noticed in my class that if you didn’t get the basics down, you were going to have a bad time for the rest of the month. </p>
<p>3) What do I have to memorize for the test (conversions, colors, etc)
Conversions, flame and solution colors, geometric shapes, strong acids/bases, nuclear particles(alpha, beta, etc.), and periodic trends. </p>
<p>Since they’re “the easiest”, your assured that you get every multiple choice and free response question right on the exam? And if I gave you a problem, you’d get it right?</p>
<p>The hardest chapter is organic chemistry of you’re a weak memorizer, but it doesn’t encompass much of the test at all. If you’re weak at math, kinetics is difficult.</p>
<p>Say you have an acidic solution of 200 ml 1.5 M HCN and you add 100 ml 2 M NaOH. It’s pH is 3.7. (These numbers are made up.) If you add 300 ml of 1 M HCl or 1 M KOH the current solution, the pH will either go up or down. But since it’s a buffers the change won’t be as much as it would’ve been. </p>
<p>(Someone correct me or explain this better if possible.)</p>
<p>hmmm… I’d say kinetics or buffers were the hardest for me. One thing I’d say though is that lab time is really essential for AP chem. I know you’re self studying it, but if there is any way you can get the lab time to perform some labs, perhaps a titration or identifying ion lab, it will really help. Maybe talk to your school chem teacher. I know for me, being in the lab so much helped me with predicting reactants and just understanding the material in general. I really cannot over stress the importance of lab work and applying the calculations you learn from the book to your own data. </p>
<p>Also, as for what you have to memorize, you should know the basic cations and anions and their basic colors (if they have one). You should also know some of the products in common redox reactions, especially those with Mn. Also, make sure you memorize the weak and strong acids and bases as well as the different shapes and bond-angles of molecules.</p>
<p>Here are the links to two very good pages with stuff that if you memorize before the test, it will be a lot easier. It helped me get a 5:</p>
