Uncertainty of a Hydrogen Atom from the ground-state energy can be estimated using the Heisenberg's uncertainty principle. Assuming the size of a hydrogen atom is approximately 0.1 nm, prove that the ground state energy of a Hydrogen atom is approximately leV inside a one-dimensional box of length L=0.Inm.

Choose all the answers that apply. ionic compounds dissolve easily in water do not dissolve in water have low melting points have high melting points conduct electricity when melted

The small bags of silica gel you often see in a new shoe box are placed there to control humidity. despite its name, silica gel is a solid. it is a chemically inert, highly porous, amorphous form of sio2. because water vapor readily adsorbs onto the surface of silica gel, it acts as a desiccant. despite not knowing mechanistic details of the adsorption of water onto silica gel, from the information provided you should be able to make an educated guess about the thermodynamic characteristics of the process. predict the signs for δg, δh, and δs for the adsorption of water.
