The specific heat for liquid argon and gaseous argon is 25.0 j/mol·°c and 20.8 j/mol·°c, respectively. the enthalpy of vaporization of argon is 6506 j/mol. how much energy is required to convert 1 mole of liquid ar from 5°c below its boiling point to 1 mole of gaseous ar at 5°c above its boiling point? 6631 j229 j6735 j125 j6610 j

The number at the end of an isotope’s name is the number.

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.
