<p>Does anyone know any good resources that I can use to learn how to write the random equations on the FR portion of the AP Chemistry test? I use mostly guesswork now but I know that won't cut it for the actual test.</p>
<p>It is guesswork. Seriously, with the exception of redox equations, I’ve never seen a non-guesswork way of doing it. And even in redox, balancing the half-reactions is guesswork.</p>
<p>Practice a lot, learn to see trends and remember that AP questions normally won’t be mind-bogglingly complicated - the easiest way is normally the correct way.</p>
<p>I find the redox ones hard because idk how much the charge changes in the products.</p>
