Hey, I'm having trouble understanding the trends of the oxidation states for the first row of the transition metals
-my prof said that Cu is the only metal that forms a stable +1 oxidation state. But, I've done a question in hmwrk that had Cu+1 as unstable with respect to disproportionation how...
So I have a proof and I can't follow the process, I think its because I haven't learned how to do partial derivatives or I've forgotten, anyways can someone tell me if this is a rule in calculus
(∂Cv/∂V)T=0
I've gotten to
[(∂/∂V)(∂U/∂T)V]T
and the proof I have goes to...
