Question 1 if we mixed 45cm^3 of 2m naoh with 20cm^3 of 1m hcl and obtained a temperature difference of 9.4°c, what would be the heat of reaction, the enthalpy? . question 2 if we added 10cm^3 hcl of an unknown concentration to 30cm^3 of 2m naoh and obtained a temperature change of 4.5°c and then added 20cm^3 of the same unknown acid to 30cm^3 of 2m naoh and obtained a temperature change of 9.0°c, what is the concentration of the acid? use the enthalpy value from question 1

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.
