    Zeff and ionization energies

    Hey guys, Im having trouble understanding/explaining some of the trends in ionization energy with calculated Zeff by slaters rules. For example I was asked why is the 3rd ionization energy for Be greater then the 3rd ionization energy for O My train of thought was to say its pulling an...

    Redox trends of the first row transition metals

    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...

    Partial derivative in thermodynamics

    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...
