1. How does hydrogen bonding affect water molecules?
A Hydrogen bonding holds two hydrogen atoms to one oxygen atom in a
water molecule.
B Hydrogen bonding causes the polarity and bent angle of a water
molecule.
C Hydrogen bonding is the main force that attracts water molecules to
one another.

C Hydrogen bonding is the main force that attracts water molecules to

one another.

Explanation:

Hydrogen bonding affects water molecules because, it is the main force which holds and attracts water molecules to one another.

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!
