The substance in a mixture that is dissolved is called the:
a) Solution.
b) Solvent.
c) Solute.
d) Aqueous solution.

A solution in which water is the solvent is called a(n) _______________ solution.

a) Polar.

b) Aqueous.

c) Hydrophobic.

d)  Complete.

What is the charge of the solute molecule in the image below based on the polarity of water?

a) Positively charged.

b) Negatively charged.

c) Uncharged.

d) Non-polar and hydrophobic.

The components of a heterogenous solution are ________________ distributed throughout.

a) Equally. 

b) Unequally.

c) Uniformly.

Hydrophobic molecules:

a) Are polar covalent molecules.

b) Easily dissolve in water.

c) Are nonpolar water 'fearing' molecules. 

d) Are nonpolar water 'loving' molecules.

Determine the following:

a. The molarity of a solution with 0.5 moles of glucose per liter of water.

b. The concentration (in weight/volume percent) of a solution that contains 20 grams of sodium chloride per liter of water.

c. The concentration (in mg/dL) of a solution with 1 gram of lactic acid per 100 mL of solution.

d. The molarity of a solution with 1 mmol of solute in 1 L of water.

Explain how the polarity of water molecules makes water an excellent solvent.
