Calculating the Decomposition of CaCO3 Calcium carbonate (CaCO3), an important component of coral reefs, can decompose when heated, forming calcium oxide (CaO) and carbon dioxide (CO2) according to the equation below: CaCO3 es002-1. Jpg CaO CO2 How many moles of CaO form when 98. 60 g CaCO3 decompose? 98. 60 g CaCO3 = mol CaO.

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.
