A large number in front of a compound designates how many units there are of that compound. Parentheses can be used to designate a special structure, where other molecules are attached to the larger, complex molecule.
Hydrogen sulfide has a low boiling point because it is only a slightly polar molecule, meaning that it only has weak dipole-dipole intermolecular forces. Because of its relatively weak intermolecular forces, it has a low boiling point.
Answer:
