Fill a glass with water above the rim. It forms a domed surface. Add a paper clip and watch it float, even though

the paper clip is made of a metal that is denser than water. This is due to water's surface tension. Water has several
very unique properties, like surface tension, cohesion, and adhesion because water
is the universal solvent and can hold anything, even paper clips.
is polar and every water molecule electrically attracts the neighboring
water molecules.
bonds like metals so water molecules forms crystal lattice structure when
in a container
is polar and tends to attract metallic substances like the material that
makes up the paper clip.

Answer: (B) is polar and every water molecule electrically attracts the neighboring water molecules.

Step-by-step explanation:

Had a quiz on this ;) The guy above me never answered the question.

Answer:

Water has several very unique properties, like surface tension, cohesion, and adhesion because water is polar and every water molecule electrically attracts the neighboring water molecules.

Step-by-step explanation:

Water is a universal solvent and has several unique properties like surface tension, adhesion, cohesion, high specific heat, etc.

In a water molecule, the oxygen atom's nucleus attracts electrons more strongly than the nuclei of hydrogen atoms. The negatively charged electrons are pulled toward the oxygen atom's nucleus and away from the hydrogen atom nuclei. As a result, a negative electrical charge occurs in the middle part of the water molecule near the oxygen atom and a positive charge near the other parts of the molecule (hydrogen atoms). This unequal distribution of electrical charge between different parts of the water molecule (polarity) makes it a polar molecule.

The positive part of one water molecule (hydrogen atoms) is attracted to the negative parts of neighboring water molecules and as a result, hydrogen bonds are formed between hydrogen and oxygen atoms of adjacent water molecules. These hydrogen bonds between molecules help hold water molecules together.
