Solve Part C, Part D, Part E: Part C: Question: Imagine riding in a car or bus. Describe four uses of petrochemical products that are related to the manufacture or use of motor vehicles.

Part D: Question: Identify the oxidizing agent and the reducing agent in the reaction CuS(s) + H2(g) ---> Cu(s) + H2S(g).

Part E: In the reaction Sn(s) + Br2(l) ---> SnBr2(s) , what is being oxidized and what is being reduced?

Astudent is asked to identify and element that is pale yellow brittle solid and does not conduct electricity. at which location in this periodic table would the element most likely be found?

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.

How can the periodic table be used to predict the behavior of elements?
