Compute reaction rates for all seven trials
reaction rate is usually computed as a change in concentration (e. g., molarity) per change in time. the tablet is not pure nahco3, so the molarity cannot be computed accurately. (in addition, the quantities in this lab are quite small, and the resulting values would be small decimal values.) instead, compute the following as a measurement of reaction rate.

Which statement describes james chadwick’s discovery.

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.
