Revisit the model of mixing water and ethanol that you drew after the hands-on experiment. Do the components in that initial model explain your observations of water and ethanol? If not, what revisions would you make to your model?

b..

is the correct one

explanation:

covalent bonds form as valence electrons are shared between two atoms. lewis structures and structural formulas are common ways of showing the covalent bonding in organic molecules. formal charge describes the changes in the number of valence electrons as an atom becomes bonded into a molecule.
