PLZ HELP!! WILL GIVE BRAINLIEST Two students made the Lewis dot diagrams of H2O. The diagrams are as shown.

Two visual diagrams of an H two O molecule are shown. Student As diagram on the left has oxygen at the center and connects with two hydrogen atoms by way of straight lines. There are two pairs of dots above the oxygen atom. Student Bs diagram is identical except it has one pair of dots and instead of lines, and it has an arrow between the oxygen and each hydrogen.

Which student drew the correct Lewis dot diagram?

Only Student A

Only Student B

Both Student A and Student B

Neither Student A nor Student B

It is only student A

Explanation:

I just took the quiz and got a 100% good luck to whever is reading this.

yes it is balanced

answer : (a) volume of the gas = 8.67 ×   l

                (b) second virial coefficient b = -1.21226 l/mole

solution :   given,     t = 300k

                                p = 20atm

                                z = 0.86

                                n = 8.2 mmoles = 8.2 × moles

                                r =   0.082 l atm/k/mol

        find,     (a) volume of gas   and (b) second virial coefficient b at 300k.

formula used :            

                          and            

(a)            

                    = \times 0.082\times 300}{20}[/tex]

                    = 8.67 ×   l

(b)      

                    = (0.00867-1) × 8.659

                    = - 8.5839 l/mole
