inter-molecular force between two polar molecules consisting of H bonded to N, O, or F

Question 15

Chemical Bond

Answer 15

the transfer or sharing of electrons between two atoms such that a noble gas configuration is achieved (eight is great)

Question 16

BARF

Answer 16

Breaking a bond –> Absorbs energy

energy is Released –> bonds are Formed
