Chemistry Semester 2 Final Exam Review

The kinetic molecular theory describes the behavior of matter in terms of particles in motion.

• True

• False

Molecular solids are good conductors of heat and electricity because the molecules are held together by ionic bonds.

• True

• False

In a balanced chemical equation, the total mass of the reactants is equal to the total mass of the products.

• True

• False

A molecule in the interior of a liquid is affected equally in all directions by intermolecular forces.

• True

• False

An elastic collision is one where two colliding particles both lose some of their kinetic energy.

• True

• False

Both gases and liquids can be classified as fluids because of their ability to flow.

• True

• False

Stoichiometry is the study of the relationship between the amount of reactants used and the amount of products made in a chemical reaction.

• True

• False

The atomic mass of a manganese atom is 54.94 amu, then its molar mass is 54.94 g/mol.

• True

• False

When the molecules of gases are heated, the average kinetic energy of the molecules increases.

• True

• False

The intermolecular force between molecules of oxygen is dipole-dipole in nature.

• True

• False
