### Re: Week 7 Sapling

I assumed that it had not been posted yet because we're having midterm 2 this week. Week 7's Sapling assignment might end up being due at a later date if it's combined with week 8.

### Re: Noble gases as central atoms? textbook problem 2C.11

Hi! I'm not sure if this is simply an exception because I think it just depends on electronegativity.

Hi! I'm in the same boat. I've been trying to focus less on the numbers, and more on how to study effectively so I can do well on the next midterm and the final exam. If you wanted to see where you're at, I think you could calculate your current grade based on the breakdown from the syllabus.

Hi, if you click the on the 1- formal charge one more time it should change it to 2-.

I think it's just untested material . It's going to cover material from the MT1 cutoff (last 8 points of outline 2) and onwards.

I think all chemical reactions would have a limiting reagent because there will be an excess of one reactant, meaning the other one will be completely used up and limit the amount of product that can be formed.
