A particular unit cell is cubic with ions of type A located at the corners andface centers of the unit cell and ions of type B located at the midpoint ofeach edge of the cube and at the body-centered position. The ions contribute to the unit cell in the usual way (1/8 ion contribution foreach ion at the corners, etc.). (a) How many ions of each type are there per unit cell?
(b) Describe this structure as a lattice and a basis. Check to be sure that the number of ions per unit cell given by your description of the structure as a lattice and a basis is consistent with your answer to part (a).
(c) What is the coordination number of each ion?
(d) What is the name commonly given to this crystal structure?

Two flowing streams of argon gas are adiabatically mixed to form a single flow/stream. one stream is 1.5 kg/s at 400 kpa and 200 c while the second stream is 2kg/s at 500 kpa and 100 ? . it is stated that the exit state of the mixed single flow of argon gas is 150 c and 300 kpa. assuming there is no work output or input during the mixing process, does this process violate either the first or the second law or both? explain and state all your assumptions.
