10.861% / 100 = 0.10861
12.428 % / 100 = 0.12428
(0.10861 * 187.9122) + (0.12428 * 190.9407) <span>+ (0.76711 x 192.8938)</span>
= 192.1100 amu .
hope this helps!
Answer:
G<0, spontanteous
H<0, from equation
S>0, gas to solid
Explanation:
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. Water vapor readily adsorbs onto the surface of silica gel, so 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 of ΔG, ΔH, and ΔS.
