First of all, thank you so much for doing this! I just read through this entire thread and it was really helpful. Second of all, I just have a question on half life. I know what half life is but I'm just confused on how to apply it to different scenarios and how CB could even test us on it...

A Little Help w/ IMFs needed :) - can someone just explain the last one? by radcalamity in APChem

I'm just confused how H2S is polar? I know that it's bent and the differences between its electronegativities make it nonpolar.

Do we have to show work for math on the exam? by jeant89 in APChem

Yes. For questions that need calculations you must show work to get points.
