In a homonuclear molecule, you would add electrons based on the Pauli Exclusion Principle as well as Hund's rule.

For the example on Pg 170, I believe the reason it does not happen that way is because the K value is so small that acetic acid wants to remain as such without dissociating. When we add the conjugate base by adding the salt, some of it WILL be affected by equilibrium with H+ but it is not enough to ...

Another way to look at it is if the molecule as a whole has a dipole moment. A molecule is polar if one side is more negative than the other and it is attracted to the opposite charged side of another molecule.

To figure out how many orbitals there with quantum numbers n=3 and l=2, just find how many d orbitals there are specifically. Those are the number of ml values. For d orbitals, that value is 5. Hence, there are 5 orbitals with those quantum numbers.

As per my experience, I've noticed that when an organic molecule is written ( and I'll use propane as an example here ) in it's molecular formula, it is usually written as C 3 H 8 . It's structural formula, however, is CH 3 CH 2 CH 3 . Usually when the molecule is written in this expanded form, it i...

The way I go about it is that I memorize the ones that I find particularly confusing. There is no other roundabout way to do this I think. I can help you with the chlorate though. Stuff like chlorates usually mean that you have the maximum amount of Oxygen bound to a Chlorine atom (ClO3-). I would r...
