A 75.0 mL portion of a 1.20 M solution is diluted to a total volume of 208 mL. A 104 mL portion of that solution is diluted by adding 189 mL of water. What is the final concentration? Assume the volumes are additive. concentration:_M

Based on its chemical properties, identify the position of each chemical family on the periodic table.

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.
