GeF3H is formed from GeH4 and GeF4in the combination reaction: GeH4 + 3GeF4 → 4GeF3H If the reaction yield is 83%, how many moles of GeF4are needed to produce 8.00 mol of GeF3H?

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.
