Which is a way that the model of the atom became more accurate due to new investigations? select one: a. experiments showed that the atom is made of smaller particles. b. neutrons were detected orbiting the nucleus. c. cathode-ray tube experiments showed that the atom is indivisible. d. thomson showed that the atom contains alpha particles.

What is the formula that this ionic compounds could form sr2+p3-o2-

Explanation for basic character?

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.
