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.

a). in this case, dh> 0 and sd> 0. if t becomes larger, the term "-tds" will become more negative. at some point, it is possible that -dts will be more negative than the dh is positive, and the reaction will become spontaneous. this is probably the correct answer, but you should look at all of the other possibilities and make sure of that.
