Select ALL of the correct images. Identify the models that represent a mixture of two compounds. Models A through C 2 spheres attached to each other, with 6 smaller spheres attached around their outsides 3 identical spheres attached to each other 1 medium sized sphere attached to 2 small spheres, and 1 large sphere attached to 2 small spheres. Model A Model B Model C Models D through F 2 spheres attached to each other. 1 larger sphere on its own. 2 spheres attached to each other. 1 smaller sphere on its own. 2 medium sized spheres attached to each other and to 2 small spheres, and 1 large sphere attached to 1 small sphere. Model D Model E Model F Group of answer choices B F C A E D

you need to have a picture of the atom that way we can answer it

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
