Using the Hume-Rothery rules:
(a) Determine if Ni should dissolve easily in Cu. Show that your determination is correct by providing the Cu-rich side of the appropriate equilibrium phase diagram.
(b) Determine if Pb should dissolve easily in Cu. Again, show your answer is correct by providing the Cu-rich side of the appropriate equilibrium phase diagram.
At 63.5C the vapor pressure ofH2O is 175 torr, and that of ethanol,C2H5OH, is 400 torr. A solution is madeby mixing equal masses of H2O andC2H5OH. What is the molality of ethanol in the solution
