Oh I lost some words I mean if one of the two mole fraction is known and the other is known so C=1 what is the correct answer ? maximum number of phase is 3 or 4?

Homework Statement Acording to the Gibbs phase rule, what is the maximum number of phases that one may observe for a binary mixture in equilibrium? Homework Equations phase rule F=C-P+2 The Attempt at a Solution It says binary mixture but does it mean there are 2 component(C=2)? I think...

Thanks for your answer.

For the problem of particle in a 1D box V(x)=0 for 0≦x≦a ∞ for anywhere outside the box I know that Hamiltonian operator commutes with momentum operator so they should have smae eigenfunction but it's obvious that the wavefunction (2/a)^1/2sin(nπx/a) is not a eigenfunction of linear...

Oh I see thank you.

I mean Nsin(nπx/a) is the result of boundary conditions but Ae^(ikx)+Be^(-ikx) has not been subjected to boundary conditions yet. It's a free particle, and its potential is not a function of x . And you said they only commute if the potential is not a function of x. So I ask second time and I...

Thanks for your help. But I still have a question: Does "translationally invariant" mean the general solution of Hamiltonian operator for free particle used and no boundary condition? I have substituted the solution Ae^(ikx)+Be^(-ikx) but it is still not an eigenfunction of mometum operator.

Thanks for your reply. But I still need to rank their order without data and need to explain my answer. I already know their oxidation state are +6. And then I don't know how to proceed.

the three complexes CrO42- Mno42- FeO42- which is the order for their oxidizing power? And why?

Hamiltonian operator commutes with the linear momentum operator and for a particle in the box its wavefunction is Nsin(nπx/a) , N is the normalization constant But I found this wavefuntion is not a eigenfuntion for the momentum operator, why? Isn't the two operators commut with each other?
