Based on the description of the demonstration, were the bubbles that formed more dense than the surround-
ing water, or less dense than the surrounding water?
F. More dense; the bubbles sank to the bottom after
formation.
G. More dense; the bubbles floated to the surface of
the beaker after formation.
H. Less dense; the bubbles sank to the bottom after
formation.
J. Less dense; the bubbles floated to the surface after
formation.

Which buffer would be better able to hold a steady ph on the addition of strong acid, buffer 1 or buffer 2? explain. buffer 1: a solution containing 0.10 m nh4cl and 1 m nh3. buffer 2: a solution containing 1 m nh4cl and 0.10 m nh3

If blood contains 150g of hemoglobin per liter of blood, how much hemoglobin would be contained in 10 ml of blood

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.
