What is the difference between a heterogeneous mixture and a homogeneous mixture?

• A heterogeneous mixture contains multiple substances, while a homogeneous mixture contains only one substance

• A heterogeneous mixture has a uniform composition, while a homogeneous mixture has a non-uniform composition

• A heterogeneous mixture has a non-uniform composition, while a homogeneous mixture has a uniform composition

• A heterogeneous mixture contains only one substance, while a homogeneous mixture contains multiple substances

What is a solution?

• A heterogeneous mixture with large particles

• A mixture that cannot be separated into its components

• A mixture that contains water as the solvent

• A homogeneous mixture with small particles

What is the solvent in a solution?

• The substance present in a lesser amount

• The substance present in a larger amount

• The substance that dissolves in the solution

• The substance that cannot be separated from the solution

What is an electrolyte?

• A substance that conducts an electric current in water

• A substance that does not conduct an electric current in water

• A substance that dissolves completely in water

• A substance that does not dissolve in water

What is the difference between a strong electrolyte and a weak electrolyte?

• A strong electrolyte dissociates completely in water, while a weak electrolyte dissociates partially in water

• A strong electrolyte does not conduct electricity, while a weak electrolyte conducts electricity

• A strong electrolyte contains only one type of ion, while a weak electrolyte contains multiple types of ions

• A strong electrolyte is a solid, while a weak electrolyte is a liquid

What is solubility?

• The amount of solvent that dissolves in a given amount of solute

• The ability of a substance to dissolve in water

• The amount of solute that dissolves in a given amount of solvent

• The ability of a substance to conduct electricity

In general, what types of compounds are soluble in water?

• Organic compounds

• Metallic compounds

• Nonpolar compounds

• Ionic and polar covalent compounds

What is the molarity (M) of a solution?

• The number of grams of solvent per liter of solution

• The number of moles of solute per liter of solution

• The number of grams of solute per liter of solution

• The number of moles of solvent per liter of solution

What is the solubility of most ionic and molecular solids as temperature increases?

• It depends on the specific compound

• It generally increases

• It generally decreases

• It remains constant

What is a supersaturated solution?

• A solution that contains no solute

• A solution that contains more than the predicted maximum amount of solute at a given temperature

• A solution that contains less than the maximum amount of solute that can dissolve

• A solution that contains the maximum amount of solute that can dissolve
