State your observations upon addition of the hydrogen peroxide solution to the mixture at this point. Write two half reactions, one for the H2O2 and one for the cobalt complex and the net redox reaction that occurs between these two reagents at this point in the synthesis showing products formed. A side reaction should have been observed at this point also, namely a strong effervescence of the solution upon the peroxide addition. Was this observed

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.

Take a look at this dandelion. the yellow flower on the right is pollinated and the seeds on the left are transported by

The picture represents the process that produces most of the energy used by living organisms on earth. which process is represented in the picture? a) the magnetic attraction between two hydrogen nuclei. b) the fusion of hydrogen nuclei to produce a helium nucleus in the core of the sun. c) the fission of hydrogen nuclei to produce a helium nucleus in the core of the sun. d) the chemical reaction between hydrogen nuclei to produce a helium nucleus in earth's atmosphere.
