Re: After Stoichiometric/Equivalence Pt

I think stoichiometric pt is when they have the same number of moles not the same molarity. Answering your question, if you add more base to a weak acid obviously the solution will become more basic. The rate of this change is illustrated in the titration curve.

Re: Coordination Number

I'm not sure, but you can find question on it in the quiz 3 prep.

Coordination Number

Are there any tricks to figuring out the coordination number of a molecule?

Re: How to determine if ligands are polydentates?

I think the number of lone pairs on separate atoms in the ligand for the transition metal to bind to determines if the ligand is monodentate or polydentate. Since H2O has both lone pairs on one oxygen atom, it is monodentate.

Re: Z>8, Z<8

Why does an atom with an atomic number >/= 8 have the 2pi and 2 sigma orbitals switch? What is the reason for this switch?

Re: Electron Configurations Exceptions?

If you can make the d orbital consisting of 5 or 10 electrons using the electrons from that s orbital do you do so? (Ex: Quiz 2 #2 electron configuration of Fe+3)

Periods 15 and 14 relationship

What is the relationship between these two periods for electron affinity? One of the answers for a homework problem in Ch. 2 stated that carbon has a higher electron affinity than nitrogen. Why is that?
