Properties of Water (14)

Water readily dissociates ionic compounds, dissolves covalent molecules, and hydrates the smaller particles. This is most likely because

Water is a polar molecule.

City A is located along the shore of an ocean. City B is at the same latitude and altitude, but it is located about 124 miles (200 km) inland, away from any large bodies of water. Which of the following statements most likely describe these two cities? Check all that apply.

A - In the summer, the daytime temperature in City A is typically lower than the daytime temperature in City B. B - In the winter, the daytime temperature in City B is typically lower than the daytime temperature in City A.

The attraction forces between mercury atoms in liquid mercury are stronger than the intermolecular forces between water molecules. Which of the following is most likely true about mercury?

A - It has a higher surface tension than does water.

Which of these statements would be true if the water molecule was linear instead of bent? Check all that apply.

A - Water molecules are polar. C - Water molecules undergo hydrogen bonding. E - Water molecules have a bent geometry.

Water's strong hydrogen bonds result in which physical properties? Check all that apply.

A - high boiling point C - high specific heat E - density of ice being less than that of liquid water

Which of these substances most likely dissolve in water? Check all that apply.

B - glucose, a polar organic compound C - silver nitrate, an ionic compound

Which functions of water in living systems would still be possible if water was not polar and did not form hydrogen bonds? Check all that apply.

C - providing body support by exerting pressure on cell walls D - providing body support through buoyancy E - transport of nutrients within organisms

When water breaks apart an ionic compound into cations and anions:

Dissociation

When water breaks down substances and surrounds individual molecules or particles:

Dissolving

When water surrounds substances that have been "broken apart":

Hydration

Dissolving salt in water reduces the intermolecular forces between water molecules. What most likely happens to the surface tension of water when salt is dissolved in it?

It decreases.
