There are two opposing processes that occur in a solution in contact with undissoved solute. these are dissolving

a. supersaturation;
b. hydration;
c. crystallization;
d. solvation

c. crystallization

Explanation:

Crystallization is defined as the process in which the  atoms or molecules solidifies into a highly structured form known as a crystal.

This is also referred to as slow precipitation of crystals.

It can also be stated as the separation and purification technique of solid-liquid as the mass transfer takes place from a solution to a solid crystalline phase of pure substance.

chemical energy is stored in the chemical bonds of atoms and molecules. it can only be seen when it is released in a chemical reaction. when chemical energy is released, the substance from which the energy came is often changed into an entirely different substance.

this chemical reaction releases energy in the form of light and heat. chemical energy is the potential energy stored in the arrangement of atoms within molecules. breaking chemical bonds requires energy, while forming new chemical bonds releases energy.

the atp molecule can store energy in the form of a high energy phosphate bond joining the terminal phosphate group to the rest of the molecule. in this form,energy can be stored at one location, then moved from one part of the cell to another, where it can be released to drive other biochemical reactions.

d. temperate deciduous forest
