Why is there so much anomalies in water properties (as mentioned in the site above)? How many are really unsolved and would anyone here happen to know the answer to each puzzle?

There is nothing strange in fact that some small molecules of light elements behave differently than it would be logical if you look at trends determined for heavier molecules/elements. Effects that tend to be hidden by the more prominent effects present in large molecules become dominating in smaller molecules, hence the differences.

Anomalies are not unique to water. It seems the key factor is the tetrahedral coordination of molecules in the solvation shell. Other "tetrahedral" liquids are e.g. silica, silicon, and germanium.
