CuCl2 + 2 NaNO3 → Cu(NO3)2 + 2 NaCl 1) If 1.56 moles of copper (II) chloride, CuCl2 react with 2.02 moles of sodium nitrate, NaNO3, how
many moles of sodium chloride, NaCl, can be formed? What are the limiting and excess
reactants? How many grams of the excess reactant remain when the reaction stops? If 1.26
moles of sodium chloride are actually produced, what is the percent yield of sodium chloride?

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.
