A water molecule is bound by hydrogen bonds to 3 other water
A water molecule is bound by hydrogen bonds to 3 other water molecules (only). From this
information you know:
a) This water molecule is not currently found in a solid phase (ice).
b) This water molecule is not currently found in a gaseous phase.
c) This water molecule is not currently found in a liquid phase.
d) a) and b)
e) You cannot know any of the above
Solution
Water molecules are bound hydrogen bonds which are very weak compared to other bonds. Hydrogen bonds are formed easily when two water molecules come close together but are easily broken when the water molecules move apart again. At room temperature, the water exists as a liquid due to tiny, weak hydrogen bonds holding many water molecules together. In this state single water molecule is bound to 3 other water molecules by hydrogen bond.
So this information states that This water molecule is not currently found in a solid phase (ice) and This water molecule is not currently found in a gaseous phase.
The answer is d
