Match each of the following intermolecular forces to the corresponding description to the nature of the attraction. ion-dipole dipole-dipole hydrogen bond london dispersion a. attractions between oppositely charged ends of two or more polar molecules. b. attraction between a partially positively charged h-atom attached to a highly electronegative atoms (i. e. n, o, or f) and the lone pair of another electronegative atom. c. attraction between an instantaneous dipole and an induced dipole on a neighboring atom or molecule, do to the distortion of the electron shape surrounding the atoms. d. attraction between a charged ion and the end of a dipole with the opposite partial charge.

elements make up everything, and they combine to make compounds.

the answer is c

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
