107.3 degrees.

Front

When a molecular solid melts or boils, which type of forces break?

Back

Intermolecular forces.

Front

Define a polar covalent bond.

Back

A type of chemical bond where a pair of electrons is unequally shared between two atoms.

Front

What is the significance of formal charge in Lewis structures?

Back

Formal charge helps to determine the most stable Lewis structure by indicating the distribution of electrons.

Front

What is the VSEPR theory used for?

Back

VSEPR theory is used to predict the geometry of individual molecules based on the repulsion between electron pairs.

Front

How many lone pairs does nitrogen have in ammonia (NH3)?

Back

1 lone pair.

Front

What is the difference between intramolecular and intermolecular forces?

Back

Intramolecular forces are the forces within a molecule that hold the atoms together, while intermolecular forces are the forces between molecules.
