Answer:
Option (c) is correct.
Explanation:
According to 2nd law of thermodynamics, every spontaneous process is associated with increase in entropy (
).
As sodium acetate crystallizes out spontaneously therefore it is associated with
.
During crystallization, bond formation takes place which results evolution of heat. In other words, crystallization phenomenon is exothermic (
).
So, the given crystallization process renders the following thermodynamic quantities-
J/K and
J
Option (c) is correct.

The coefficients are the key.
Create a proportion with them, and the molar mass, and then solve for x:

Answer:
Explanation:
A supersaturated solution is unstable—it contains more solute (in this case, sugar) than can stay in solution—so as the temperature decreases, the sugar comes out of the solution, forming crystals. The lower the temperature, the more molecules join the sugar crystals, and that is how rock candy is created.
