The work has not been graded but I like the output that was submitted to me. Is it possible for the same prof to do the next assignment I will be submitting? If possible, I will greatly appreciate it.
I have three more answers I need to help my son with – thanks in advance to anyone who can help and please explain the answer:
1) Draw a possible band diagram of Al (a metal) Show the valence band, the conduction band and the bandgap. Compare the Al diagram with a possible diagram of Si (a semiconductor) and diagram for p-type silicon.
2) A crystal has a cubic lattice. The unit cell contains the anion (A) at each corner of the cube and a cation B at the center of the cube. What is the formula of this compound? You must explain your answer? Give an example of a real compound that adopts this structure.
3) For H2O the heat of fusion if 6 kJ/mole and the heat if vaporization is 41 kJ mole. Predict the heat of sublimation of water
