Chemistry 2 Unit review(1)

Front

What is a solute?

Back

A solute is a substance that is dissolved in a solvent to form a solution.

Front

What is a solvent?

Back

A solvent is a substance that dissolves a solute, resulting in a solution.

Front

What is the main difference between physical and chemical changes?

Back

Physical changes only affect the physical properties of a substance, while chemical changes result in the formation of new substances.

Front

What is solubility?

Back

Solubility is the maximum amount of a solute that can be dissolved in a given amount of solvent at a specific temperature.

Front

How do we make a dilution?

Back

To make a dilution, we add more solvent to the solution.

Front

How does temperature affect the rate of dissolution?

Back

Temperature affects the rate of dissolution by increasing or decreasing the kinetic energy of the solvent molecules, which affects the frequency of collisions with the solute.

Front

What is a saturated solution?

Back

A saturated solution is a solution that contains the maximum amount of solute that can be dissolved at a given temperature.

Front

What is the difference between concentrated and diluted solutions?

Back

A concentrated solution has a large amount of solute relative to the amount of solvent, while a diluted solution has a small amount of solute relative to the solvent.

Front

What happens during a chemical change?

Back

During a chemical change, the composition of a substance changes, resulting in the formation of one or more new substances.

Front

What is an example of a physical change?

Back

An example of a physical change is melting ice into water.
