EXPERIMENT 2: The initial molarity of the Cu2+ and Zn2+ solutions used in the setup of the electrochemical cell was 1 M. Explain why the voltage was not equal to the standard reduction potential for the Cu/Zn redox reaction at all times during the experiment.

What layer of the atmosphere is directly above the troposphere?

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 many grams of ammonia would be produced by the decomposition of 16.93 mlof hydrazine? (the density of hydrazine is 1.021g/ml)
