What does the angular momentum quantum number determine. Check all that apply. A.) the overall size of an orbital B.) the energy of the electron on the outer shell
a sample of 4.0 mole O2 is originally confined to 20 L at 270 K and then undergoes adiabatic expansion against a constant pressure of 600 torr until the volume has tripled. calculate q, w, delta T, delta U and delta H
