The reason h2s exists as a gas while h2o exists as a liquid at room temperature is because:
h2s has more electrons than h2o, causing a larger dispersion.
h2o has a lower boiling point than h2s.
h2s possesses hydrogen bonds, while h2o only possesses london dispersion forces.
h2o possesses hydrogen bonding, while h2s does not.
