Q3. A student wanted to make blue copper sulfate crystals from green copper carbonate powder
CaHeK987 [17]

Heat the sulfuric acid solution and adding copper carbonate in it.

<h3>Improvement require in this experiment</h3>

The method could be improved by heating sulfuric acid solution and add copper carbonate into the solution of sulfuric acid. Add the copper carbonate until it is present in excess amount. After that filter the extra amount of copper carbonate so in this way the blue copper sulfate crystals are produced.

The molar mass of BeBr2 is
valentina_108 [34]

Answer:

168.812 g/mol

Explanation:

atomic mass. of Be= 9.012

atomic mass of Br= 79.90

because there is a 2 after Br you double the atomic mass

79.90(2)= 159.8

To find the molar mass add the atomic masses of each element

9.012+159.8=168.812

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.

G<0, spontanteous

H<0, from equation
