Hi. In Appendix 2a it shows that the enthalpy of formation for N2 is actually 0, so it doesn't need to be included in the equation. Hope this helps!

Re: Naming Coordination Compounds

If a molecule is polydentate ie: en, dien, or oxalato, you use bis and tris for the amount of that molecule.

ex: Na3[Co(C2O4)3] would be sodium tris(oxalato) cobaltate III

You use di and tri with non-polydentate molecules (most other ligands we learned).

Re: 12.65 (e) and (f)

I have a similar question for number 12.69 part B. It says calculate the pH of 0.055M AlCl3 and then the reaction, in the solution manual, has the reaction as Al(h20)6^3+. Why is the Cl gone? and Are all metals going to bond with water molecules?
Thanks

Re: Sigma and Pi Bonds

Its largely based on the interaction of bonds. A sigma bond is between two orbitals, each with 1 electron, and interacts from end-to-end. It has cylindrical symmetry. A pi bond, forms when orbitals overlap side by side, but most importantly is in addition to a sigma bond! It can't rotate and the bon...
