What is the change in enthalpy when 180 g of water vapor condenses at 100oC? (ΔHv = 40.67 kJ/mol) options:

407 kJ

565 kJ

–407 kJ

–565 kJ

hurricanes form in warm water

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: )
