2.3.1 Water: Hydrogen Bonding, Solubility, and Specific Heat Flashcards
1
Q
water
A
- a polar molecule that can act as a solvent through the formation of hydration shells.
- bonds between oxygen and hydrogen are polar
covalent bonds, which result in a partial negative charge on the oxygen atom and a partial positive charge on the hydrogen atoms - separate the ions from each other by forming
hydration shells around them.
2
Q
solubility
A
- of a substance refers to its ability to dissolve other substances.
3
Q
hydrogen bonds
A
- water molecules are held together
4
Q
specific heat
A
- of water, is the amount of heat needed to raise the
temperature of one gram by one degree Celsius.
5
Q
Which of the following type(s) of compounds would you expect to be soluble in water?
A
- polar compounds
6
Q
The intermolecular bonds in water are
A
- hydrogen bonds
7
Q
If a compound has a low specific heat, that means
A
- that the amount of heat required to increase the temperature of one gram of the compound is low
8
Q
The intramolecular bonds in water are
A
- polar covalent
9
Q
Which of the following is an effect of the polarity of the water molecule?
A
- The polarity of water molecules requires it to absorb a lot of heat to change from liquid to gas.
10
Q
The bonds broken when water vaporizes to form a gas are
A
- hydrogen bonds
