Question

1. a sample of liquid nh₃ is brought to its boiling point. will the hydrogen bonds break, or will the covalent bonds break at the boiling point temperature?

Explanation:

Boiling is a physical change. At the boiling - point of liquid NH₃, the energy is used to overcome the intermolecular forces, specifically the hydrogen bonds. Covalent bonds within the NH₃ molecule are intramolecular and require much more energy to break. They remain intact during boiling.

Answer:

The hydrogen bonds will break, and the covalent bonds will not break.
