Dissociation energy and Molecular orbital energy level diagram
Can we know the relative dissociation energy by comparing at different molecules' molecular orbital energy level diagram?

Electron-donating properties
I do not understand why CH3 has electron donating properties which make acetic acid a weaker acid than formic acid.

HW 11-117
Can anyone explain what does the solution manual mean for 11-117 (f)? "Because water is a liquid, it is by definition present at unit concentration, so changing the amount of water will not affect the reaction. As long as the glucose solution is dilute, its concentration can be considered uncha...

Re: HW 17.33
CO32- can be both monodentate and bidentate because of its resonance structure.
When it is monodentate, it will have two double bonds and one single bond.
When it is bidentate, it will have a single bond and one double bond shared by two c-o bonds.

Usually two carbons make an ideal spacing to form a chelate structure.
That's why only (b) works for there are two carbons in between NH3

Re: Chapter 4 Question #13 part b
109.5 degree in this case is just an approximation. The angle will change corresponding to different atoms.

HW 3.59
The question is to draw the Lewis structure of ClO.
I know it is a radical because the sum of valence electron is 13, an odd number.
However, if we are not given the electronegativity, how do we determine which atom should have the lone electron?

Re: Nodes and Nodal Planes [ENDORSED]
I have follow-up questions:
1) How to get the equation for finding the number of nodes?
2) How many nodes do 3p, 3d have? and how many nodes are there in an atom, such as a nitrogen?

Re: Question on G25
I have a basic question for G25.
If diluting a solution does not change the moles/ molecules of solute in the solution, then why does the amount of X in this question will decrease?
Doesn't the moles/ number of molecules of X have to stay the same?
