Clarification of lone pairs

Just wanted to be certain, lone pairs occupy their own region of electron density, yes?

differentiating between the two

I'm still just very confused on how to tell whether a salt is acidic or basic...can someone help explain it?

finding pH for weak acids

When you are constructing the ICE charts for these problems, do you always subtract the amount of base (in moles) by the amount of the acid (in moles) when solving for C?

ICE charts

When we are trying to find the change in concentration, how do we know whether to add or subtract x?

heisenberg uncertainty equation

I was sitting in one of the review sessions earlier today and this equation came up and I completely forgot how and when to apply it. This is probably a very vague question but can someone try to explain it?

Determining whether or not there are wavelike properties

I was reviewing the worked examples on page 12 in the 2015 version of the course reader and was a little confused. How small does the solution have to be in order to determine that it is too small to be detected?
