The molar mass of two equally sized samples of unknown gaseous compounds is shown in the table. molar mass comparison gas molar mass x is 28 g/mol y is 44 g/mol at stp, which describes the density and effusion of both gases? a.)gas x has a higher density and effuses faster than gas y. b.)gas x has a higher density and effuses slower than gas y. c.)gas x has a lower density and effuses slower than gas y. d.)gas x has a lower density and effuses faster than gas y.

Is laundry detergent an acid or a base?

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.
