Properties of Water
,1.What type of bond is labeled "2" in the diagram below?
A
ionic bond
B
hydrogen bond
C
nonpolar covalent
D
strong
2.Water is known as a polar molecule because...
A
All electrons are found near the hydrogen atoms of the molecule.
,B
Electrons are shared equally across the covalent bond.
C
Electrons are shared unequally, and found more around the oxygen, giving
it a negative charge at that end.
D
Electrons are shared unequally, and found more around the hydrogen,
giving it a negative charge at that end.
3.Capillary action is how water moves up a narrow tube such as a plant stem.
This is caused by...
A
Surface Tension
B
Evaporative Cooling
C
Solubility
D
Adhesion and Cohesion
2.In hydrogen bonding, positively charged hydrogen atoms are attracted to...
A
negatively charged atoms of other molecules.
B
neutral nonpolar molecules around the water molecule.
, C
positively charged atoms of other molecules.
D
the oxygen atom they are covalently bonded to.
3.Water forms hydrogen bonds and can dissolve many substances because it
is...
A
polar
B
nonpolar
C
acidic
D
basic
4.The attraction between water molecules and molecules of other substances.
A
adhesion
B
cohesion
C
solubility
