Exam 5: Water and Seawater

Match the term with the appropriate phrase. You may use each answer once, more than once or not at all. -change in state from liquid to gas

The overall electrical charge of most atoms is balanced because each atom contains an equal number of protons and neutrons.

Independent of the actual salinity, the ratios or proportions of the major dissolved constituents of seawater such as chloride, sodium, and magnesium are relatively constant.

All of the following statements regarding pH are true except:

Water can pile up higher than the edge of a container due to its low surface tension.

A rapid change in ocean temperature with a change in depth occurs in the:

-What is the origin of the salt ions in seawater?

Match the term with the appropriate phrase. You may use each answer once, more than once or not at all. -precipitation

Deep-ocean water contains more carbon dioxide than surface water because deep water is colder and has the ability to dissolve more gases.

As the salinity of seawater increases, its:

Match the term with the appropriate phrase. You may use each answer once, more than once or not at all. -charged atoms due to the gain or loss of one or more electrons

Match the term with the appropriate phrase. You may use each answer once, more than once or not at all. -sea ice formation

The density of seawater is affected by salinity and temperature.

Match the term with the appropriate phrase. You may use each answer once, more than once or not at all. -bonds that involve the sharing of electrons between atoms

Hydrogen bonds between water molecules are responsible for the unique chemical and physical properties of water.
