Why does the oxygen atom in a water molecule have a negative charge?
o
a. water is made of two ionic bonds.
o
b. oxygen attracts electrons more strongly than hydrogen does.
c. water is a nonpolar molécule.
d. hydrogen bonding pulls electrons toward oxygen.

the answer is b oxygen attract electrons more strongly than hydrogen does

B

Explanation:

Atoms of oxygen are electronegative and attract the shared electrons in their covalent bonds. Consequently the electrons in the water molecule spend slightly more time around the oxygen atomic center and less time around the hydrogen atomic centers. The covalent bonds are therefore polar, and the oxygen atoms have a slight negative charge

an adaptation is a change or process by which an organism takes to be better suited for its environment. for example; migration is a behavioral adaptation, this is needed because birds are not built to last extremely cold climates. there are different adaptations because there are different species needing to adjust to different things, bears don't migrate; they hibernate.
