<p>My AP Chem class just started thermochemistry (We are using the Central Science textbook, not Zumdahl which I have read a lot about on this site) and I was just wondering how big of a topic this is on the AP. I have not taken Physics yet, not even a basic course, so I am having difficulty with understanding most of the information about work and energy, etc. </p>

<p>Also, what topic are you guys up to? Our school started in September. I know some of you guys start in August so yea. </p>

<p>Thank you!</p>

<p>My class is using the same textbook (eighth edition) and we’ve also just started thermochemistry! Though we did skip to electrochemistry first.</p>

<p>According to my princeton review book, thermochemistry takes up apparently 5 of 75 questions on the test.</p>

<p>It tends to come up in the free response section, so I would try my best if I were you. Ask your teacher for supplemental materials, or ask if you can borrow an alternate textbook from him/her that might explain things in a way you might understand better. You can also look through the internet for videos ([Khan</a> Academy](<a href=“Khan Academy | Free Online Courses, Lessons & Practice”>Khan Academy | Free Online Courses, Lessons & Practice)) or other explanations.</p>

<p>I took AP Chem last year, but someone in AP Chem asked me a question the other day on effective nuclear charge. I still have my book from last year, so that would be chapter seven of your textbook.</p>

<p>Thank you both for replying! And after reading the Princeton chapter on it, I understand it now. =]</p>
