molecular orbital diagram question
i know that when z>= 8 we put the pz under px and py and that when z<8 we but the pz above px and py
but when we have something like CO, C has z=6 and O has z=8 why do we use the diagram we would use for z<8 even though O=8?

calculating PH Question [ENDORSED]
When calculating the pH at the stoichiometric point of the titration , will the chemical equilibrium equation be given to us?
for example, will Na^+ +HCOO^- +H20 <> HCOOH(aq) + OH^-(aq) +Na^+(aq) be given to us?
for example, will Na^+ +HCOO^- +H20 <> HCOOH(aq) + OH^-(aq) +Na^+(aq) be given to us?

What are the main weak acids and weak bases we should know?
what are the main strong acids and strong bases we should know?
Is knowing just the ones in the course reader O.K.?

Expansion work is work due to the change of volume in a system. Does this include when the volume decreases or only when the volume increases?
