Part A On the Sound tab, investigate briefly all the phenomena you explored with water waves above and describe any similarities in your results for sound. Specifically, describe
• wave pattern as seen on the screen
• shape and amplitude of the graph
• effect of frequency on wavelength
• effect of frequency on velocity
• pattern with two sources
•wave pattern with a single-slit barrier​

In this chemical reaction, 325 grams of barium (ba) react completely. how many moles of lithium (li) are produced?

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.
