consequence of the Heisenberg Uncertainty Principle is that in the quantum mechanical picture of the atom, the solid electrons, as pictured in earlier models of the atom, are replaced by . A. probability distributions of the electrons (electron clouds) B. concentric spheres around the nucleus C. measurable electron density in the nucleus D. fuzz on the surface of the nucleus E. concentric circles around the nucleus

atomic number of carbon is 6

electronic configuration of carbon is 1s²2s²2p²

orbital diagram of c is as shown here in the image.

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
