Despite not knowing mechanistic details of the adsorption of water onto silica gel, from the information provided, you should be
navik [9.2K]

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.

What kind of reaction is this?
zheka24 [161]

Answer:

Single replacement

Explanation:

Chemical equation:

2Al(NO₃)₃ + 3Ca    →    3Ca(NO₃)₂ + 2Al

Single replacement:

It is the reaction in which one elements replace the other element in compound.

AB + C → AC + B

All other options are incorrect because,

Double replacement:

It is the reaction in which two compound exchange their ions and form new compounds.

AB + CD → AD +CB

Synthesis reaction:

It is the reaction in which two or more simple substance react to give one or more complex product.

Decomposition reaction:

It is the reaction in which one reactant is break down into two or more product.

AB → A + B

Combustion reaction:

Reaction in substance react with oxygen and form carbon dioxide and water.
