Front

What type of bonds break when a molecular solid melts or boils?

Back

Intermolecular bonds.

Front

What property does distillation separate mixtures based on?

Back

Boiling Point.

Front

What equation is used to calculate molarity?

Back

M = mol/L.

Front

Which element has a higher boiling point: He or Ne?

Back

Ne.

Front

What are the intermolecular forces present in H2O?

Back

Hydrogen bonding and London dispersion.

Front

Define intermolecular forces.

Back

Forces that occur between molecules, affecting physical properties like boiling and melting points.

Front

What is the boiling point of a substance?

Back

The temperature at which its vapor pressure equals the external pressure.

Front

Explain the concept of molarity.

Back

Molarity is the number of moles of solute per liter of solution.

Front

What is the difference between intermolecular and intramolecular forces?

Back

Intermolecular forces are between molecules; intramolecular forces are within a molecule.

Front

List the types of intermolecular forces.

Back

Hydrogen bonding, dipole-dipole interactions, and London dispersion forces.
