### Re: Review

I normally go through the course reader for reviewing the material. I think it has almost everything that we need to know.

### Enrolling in 14BL

Can I enroll in 14B lab in my first pass and 14B lecture during my second pass or do I have to enroll in 14B lecture first???

### Re: Approximating

In order to be able to approximate X to 0, Kc should be smaller or equal to 10^-5

### Re: SOLIDS and LIQUIDS omission

No you do not include the concentration of solids and liquids when calculating the equilibrium constant. So in this case, in the ice table you should only include the concentrations of H2 and AsH3.

### Re: Setting X as 0 when calculating equilibrium conc.

when K is 10^-5 or smaller we can approximate X to be 0

### Re: Why H2O always monodentate?

So both lone pairs in H2O are on oxygen atom which means there is only one binding site with the central atom. This makes H2O monodentate.

### Re: Coordination and Naming

So polydentate is a coordination compound with more than one point where a ligand can attach itself to the central atom. Example: Oxalate [O-C(=O)-C(=O)-O]2- is a polydentate ion because the molecule can attach at either oxygen at the ends of the ion.

### Re: Sulfur Dioxide Formal Charges

So I know that SO2 is an exception and although two double bonds is the best structure of you consider the formal charges, the more common structure in one double and one single bond!!! But since in the exam we had to show which structure is better based on the formal charges, I'm thinking that two ...
