2012 Midterm #8A

I found that the E standard of the redox reaction is not 0.63V but -0.89V. When I used -0.89V as the E standard of the cell i got 0.661V for Ecell which is what they gave in the question. I was wondering if anyone else found this because it would completely change the answers.

Re: Bonding theory

With molecules that have an atom that has a charge less than 8, since the nuclear charge is less the energy difference between the filled s-orbitals and p-orbitals is less. The sigma-s and sigma*-s orbitals have electron density that is on the bond axis. Because the sigma-pz is on the same bond axis...

Re: HW 3.23

From what I believe, Chlorine can be in a positive state but it is extremely rare because of its high ionization energy and therefore high electronegativity.

Re: Electron configuration

Since Silver is in the same Group as Copper, which Professor Lavelle said was an exception to how the orbitals filled up, it is also another exception.
