GENERAL CHEMISTRY 2 (4TH QUARTER REVIEW QUIZ)

The molarity of a solution can change if the temperature changes.

• True
• False

If you dilute a solution by adding more solvent, the molarity of the solution increases.

• True
• False

To prepare a 1 M solution, you need to dissolve 1 mole of solute in 1 liter of solvent.

• True
• False

The molarity of a solution can be used to directly determine the number of moles of solute in any given volume of the solution.

• True
• False

In an isolated system, the total energy remains constant over time.

• True
• False

The internal energy of a system is the sum of the kinetic and potential energies of its particles.

• True
• False

According to the first law of thermodynamics, the change in internal energy of a system is equal to the heat added to the system plus the work done by the system on its surroundings.

• True
• False

Heat and work are both forms of energy transfer and are path-dependent functions

• True
• False

The first law of thermodynamics applies only to closed systems and not to open systems.

• True
• False

Molarity is defined as the number of moles of solute per liter of solvent.

• True
• False
