<![CDATA[<p>Here is the place to be to study about all those reactions we have to know about. Below are a set of almost 300 reactions. They are all labeled and categorized. No work other than to &quot;get to know them.&quot;<br />
			The other two are the assignments. The one set includes that 20 full examples of what is on the AP Chem test, that is, predicting reactions. The other set includes the answers. When you do each of the 20, try and get at least <strong>half</strong> right. Learn to pick out and attack the ones you know. You are not required to get them all correct! Averaging half of them is very good actually! Have fun!</p>
