Calculate the pH after 0.020 mol NaOH is added to 1.00 L of each of the solutions below. Answer with the appropriate number of significant figures. (a) 0.101 M HONH2 (Kb = 1.1 ✕ 10-8)
(b) 0.101 M HONH3Cl
(c) pure H2O
(d) a mixture containing 0.101 M HONH2 and 0.101 M HONH3Cl

i'm assuming that it's c.) red bank..

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: )
