Re: strong or weak acid

You can judge the strong and weak level from the PH value or the molecular structure(see the textbook).

Re: Energy in lewis structures

When the formal charge is 0, then the energy is the lowest.
You can check it on the textbook!

Re: What does the formal charge tell us?

I think it can judge the ability to loss or absorb electrons, and how many electrons can the atom or group loss or absorb.

Re: Reading the textbook [ENDORSED]

I think read the textbook is needed if you have time. Our lecture goes really fast and no one can get all the point in the lecture, so reading the textbook and try to understand better is necessary. It is also a good way to review.
