Passing electricity a through a molecule of water
In this molecule the electrical charges are clearly separated.
When certain molecular crystals are added to water, they are able to dissolve and break down into their original molecules, if they are affected by the interatomic hydrogen bonds that water induces. A simple answer: dissolving.
A DNA molecule is held together by its hydrogen bonds. The bonds are in between the bases of the molecule, for example cytosine and guanine. Because hydrogen bonds are weak, they are able to break apart easily and split when the molecule needs to be separated to bond with another DNA molecule for reproduction.
Water can be separated by evaporation.
Water can be separated into hydrogen and oxygen through a chemical change called electrolysis, which uses an electric current to break apart the water molecules. Boiling water is a physical change that only changes the state of the water from liquid to gas, but it does not separate the water into its component elements.
This decomposition process involves breaking the glycosidic bond between glucose and fructose in the sucrose molecule. This hydrolysis reaction requires the addition of a water molecule to break the bond, resulting in the formation of glucose and fructose molecules.
Hydrogen can be separated from water molecules :)
Sodium chloride can be separated from water by water evaporation or by distillation.
Water IS a polar molecule.
Water is a polar molecule.
Water molecule is an important and good example of polar covalent molecule
