Re: Hemoglobin vs. Myoglobin
Hi! As said in today's lecture, myoglobin is used for muscles and tissues and hemoglobin is reserved for blood. Hemoglobin has 4 myoglobin-like molecules which gives the opportunity to transport 4 oxygens (O2) at a time

No Discussion because of Thanksgiving [ENDORSED]
I have my discussion on Thursday and because of the holiday it was cancelled. Does that put us behind the other discussions now or will we be reviewing this weeks lectures and next weeks during our next discussion? I enjoy reviewing each topic with my TA and I hope we discuss ligands, etc.!

Re: Ligands
The number of ligands attached to central ion, which is actually the number of donor atoms is basically the coordination number. In other words, the number of bonds also equals the coordination sphere! For example, with [Fe(CN)6]4- everything within the bracket is inside the coordination sphere, an...

Re: Textbook 1.D 23 part c
This problem is more so asking for all possible outcomes for n=2, so it has the potential to fill 2s^2 and 2p^6 with the 2s-subshell (l=0,ml=1) and the 2p-subshell (l=1, ml=-1,0,+1 (3 spots)). I'm sorry it can be kind of confusing but I hope this helps!

Re: bond length
Hi!
So you would determine the bond length through the number of bonds (single bond being the longest and triple bond being the tightest) and the size of the atom. Hope this helps!

Re: Textbook vs Lectures vs Other Methods
Hi!
What has worked best for me is first watching the lectures, then doing the reading, then spending alot of time on the textbook and sapling questions. They give me good practice. I also go over the unit outlines and fill them out to make sure I've covered all the unit material.
