5. Which of these solutions is the most basic? Rank them from most basic to most acidic.
[H+]=1 x 10-M
[OH-]=1 x 10^M
[H*]=1 x 10-11 M
[OH^)=1 x 10-13

trigonal pyramidal

tetrahedral

trigonal planar

bent

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: )
