Answer from: teriateria

The correct answer is: polarity; hydrogen bonds.

Explanation:

Water has unique properties because of the way their atoms interact with one another, and other molecules.

A water molecule consists of 2 hydrogen atoms and 1 oxygen atom: the hydrogen atoms are very electropositive, while the oxygen atom is very electronegative.

Electronegativity is a property that describes the behavior of atoms when they interact with other elements - the more electronegative an element is, the more it attracts the electrons of other elements. The difference in electronegativity between hydrogen and oxygen is what makes the bond between these two a polar covalent one. One end of the water molecule will be negatively charged, and the other end will be positively charged: this is why it's called a polar molecule.

While a water molecule has a polar covalent bond, the bond between the water molecules with one another is given by the hydrogen bonds that are established between the hydrogen of one water molecule with the oxygen of the other water molecule.

Hydrogen bonds are weaker than covalent bonds.

answer: carbon 14 can only be used to determine the age of the organisms that were once living, and igneous rocks are non living.

explanation:

carbon 14 dating is used to determine the age of the sample by estimating the amount of carbon 14 present in the sample and then comparing it with a reference standard.carbon 14 is a isotope of carbon which is radioactive and unstable. carbon 14 is assimilated by all plants and animals throughout their life from carbon dioxide. however, one the organisms die they stop this assimilation and the carbon 14 content starts to decrease.by knowing how much of carbon 14 is left in an organism after his death, one can estimate the age of the organism. the materials whose age can be estimated by carbon 14 method are the organic compounds. however, some inorganic compounds such as aragonite shell can also be dated.however, if we consider the igneous rocks it is a non living component which never accumulated carbon 14 in it and thus, we cannot use carbon 14 dating method to estimate its age.
