- 1. Multiple ChoiceThe unique physical properties of water can be attributed tostrong hydrogen-bonding intermolecular forces.its relatively low molecular weight.its relatively high densitythe open network structure of ice.
- 2. Multiple ChoiceWhich of the following statements about water (H2O) is TRUEWater is a polar solvent which easily dissolves many polar or ionic substancesWater is a polar solvent due to its linear geometry and unshared pairs of electrons on the central oxygen atomWater has an unusually low boiling point due to the strong hydrogen bonding that occurs between molecules of waterWater is a non-polar solvent which easily dissolves many non-polar substances
