Consider RbOH → Rb+ + OH- and the following information.
AHlat = -765.01 kJ/mol
AHhydr of Rb+ = -315.2 kJ/mol
AHhydr of OH-=-532.7 kJ/mol
What is the AHsol rounded to the correct number of significant figures? Use A H sol = -A Hat + AHhydr-
-1.612.91 kJ/mol
-1,612.9 kJ/mol
-82.9 kJ/mol
-82.89 kJ/mol

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!
