2. Water is a great example of a molecule with polar covalent bonds. How does this bond affect the

behavior of the water molecule?

Answer :

Example of polar covalent molecules H-O-H(water), ammonia

Explanation:

The presence of intermolecular Hydrogen bonding makes the boiling point of water unexpectedly high, and the polar covalent nature makes it dissolve polar solute/compound

Explanation:

The constituent of a water molecule is one oxygen atom and two hydrogen atom. Oxygen is highly electronegative ( ability to pull electron closer to itself in a covalent bond) compare to hydrogen and as such it creates two poles with oxygen been partially negative and hydrogen been partially positive.  This attributes allow water to dissolve polar substances such sodium chloride, sodium hydroxide. When this substance are added to water, they are pull apart with positive sodium ion attracted to the partially positive oxygen and the chloride ions attracted to the partially positive hydrogen.

The polarity of water ice is able to float in water because of the polar nature as the molecules is extended as far as possible and are held together by the hydrogen bond. Water expands when its freezes and it  density decreases

The polar nature also of its molecules also contributes to its high boiling, freezing point and strong surface tension.

answer is: naturally occurring solid, inorganic compound or element is mineral.

minerals usually have crystalline form, that means than crystal constituents (atoms, molecules or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.

for example magnetite is a mineral of iron oxide (fe₂o₃).

calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (caco₃).

dolomite is an   carbonate mineral composed of calcium magnesium carbonate (camg(co₃)₂).
