Can someone help me im doing chemistry right now and I have a question which I have no idea how to solve and I need to show work it it needs to be shown in scientific notation (7.6x10^-1)+(2.0x10^-2)

V1t2 = v2t1 is an expression of who’s law

Ineed to find the answer of this question because i dont understand it

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.
