Consider a paramagnet. (a) Calculate the partition function for one dipole. (b) Calculate the probability of finding the dipole in the "up" state. Also calculate the probability of finding the dipole in the "down" state. (c) Now consider the whole system of N dipoles. What is the average number of dipoles in the "up" state? (d) Calculate the average of the ratio of the number of dipoles in the "up" state to the number of dipoles in the "down" state. (e) Make a sketch of the quantity calculated in d versus temperature and describe in detail what happens T = 0 and T = ∞: Make sure you say "why" the system behaves the way it does at these limits. (f) Assume that the particles are distinguishable and write down an expression for the partition function for the whole system of N dipoles. (g) Calculate the entropy of this system in terms of N, Kb, T, μ, and B.

What is selective precipitation? Under which conditions does selective precipitation occur? Match the items in the left column to the appropriate blanks in the sentences on the right. equal to 10 $K_r$ $10^3$ $K_{sp}$ anions metal cations $10^3$ times lower than $10^6$ $10^3$ times higher than $K_s$ Reset Help Selective precipitation is a process for separating metal cations in a solution, which involves the addition of a reagent that forms a precipitate with one of the dissolved metal cations but not the others. If $K_{sp}$ values differ by at least a factor of $10^3$, the compounds can be separated by selective precipitation. In the calculations, Q and $K_{sp}$ are compared to determine the concentration that triggers precipitation. The precipitation occurs when the value of Q for the precipitating compound is $10^3$ times higher than the value of $K_{sp}$
