Re: Equilibrium and Disassociation of a Diatomic Molecule (11.7)

So x^2 is derived from the ice table? Is it like a short hand? Or is it a different formula?

Re: Tricks/cheat sheet

There's a video by Mr.Causey called Naming compounds in Chemistry and he goes over roots and has cheat sheets you can use to remember what he teaches in the videos. It's old but it gets the job done.

If I'm not mistaken, I believe its the opposite way around. Lewis dot structures are important for drawing/understanding VSEPR. Lewis dot structures lead us to find the structure of these components.

The tests were being graded immediately by my TA in my discussion. She had a 9 am discussion and she was almost done grading those. It might be best to email your TA and if you are really eager maybe they will let you see it during office hours (if those are before your dis section).
