Calculate:

(a) The temperature of the liquid brass after mixing..

(b) The entropy change in this mixing process;

The heat capacities of liquid zinc and copper are 15 and 20 J/mole-K, respectively

prove that the intercepts w and q are Zg and z^, respectively.

7.21 At a fixed temperature, the molar enthalpy of an A-B solution varies with composition according to:

(a) what are the molar enthalpies of pure A and pure B?

(b) What are the partial molar enthalpies of A and B at xB = 0.5?

We respect Nature and it gives us its bounty, but in the recent past greedy money hungry corporations have made us all so destructive, so wasteful.
