An alkaline battery produces electrical energy according to the following equation. Zn(s) + 2 MnO2(s) + H2001) — Zn(OH)2(s) + Mn2O3(s)
(a) Determine the limiting reactant if 12.0 g Zn and 48.5 g MnO2 are used. (Type your answer using the format CH4 for CH4.)
(b) Determine the mass of Zn(OH)2 produced.

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.
