2. What will happen to the solute
in a jar of a sugar-water solution if
you leave it in a dark place for
several days without disturbing it?

The sugar crystals recrystallises, and settles at the bottom of the container especially if the temperature of the mixture cools down gradually with time when left undisturbed.

Explanation:

Solubility is the ability of some solids (solute) to dissolve in a liquid (solute) forming a solution. It depends on temperature, amount of solute to solvent etc.

In some cases, leaving the product undisturbed over time can revert the process, forcing the solid to recrystallise out of the solvent.

answer is: naturally occurring solid, inorganic compound or element is mineral.

minerals usually have crystalline form, that means than crystal constituents (atoms, molecules or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.

for example magnetite is a mineral of iron oxide (fe₂o₃).

calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (caco₃).

dolomite is an   carbonate mineral composed of calcium magnesium carbonate (camg(co₃)₂).
