The solvents are water (H2O) and hexane (CH/). Only water | hexane has polar bonds. Thus, water is the polar | nonpolar solvent, and hexane is the polar | nonpolar solvents

a graduated cylinder.

explanation:

can you attach the

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!
