The images show two unrelated events occurring at separate times.

Event 1: A beaker pours a clear liquid into a second beaker, also full of clear liquid, creating an orange liquid. A glass holds clear liquid, with some areas of dark blue liquid surrounded by lighter blue liquid.

Which event is most likely an example of a chemical reaction?

Event 2 because the blue color mixes throughout the liquid.

Event 1 because there is a color change.

Event 2 because the temperature is dropping in the liquid.

Event 1 because there is a release of heat and light.

What is a metal replacement reaction

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.

Air can be considered a mixture. which statement does not explain why?
