Write equations showing how each of the following weak bases ionizes water to form oh-.

a.) co3^2-. express your answer as a chemical equation.
b.) c6h5nh2. express your answer as a chemical equation.
c.) c2h5nh2. express your answer as a chemical equation.

a. carbonate + water ⇄ hydroxide + carbonic acid

b. c6h5nh2 + water ⇄ hydroxide + c6h5nh3+

c. c2h5nh2 + water ⇄ hydroxide + c2h5nh2+

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!

if you need further assistance, let me know: )
