Several salts of lead are only slightly soluble in water. These are PbCl2, PbI2, PbS and PbCO3.Which of these would be more soluble in acid solution compared with water

How would you reduce the volume of gas

How many moles are in 43.9 l of oxygen

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.
