2. What net ionic equation describes the reaction that occurs when Al2(SO4)3(aq) and Na3PO4(aq) are mixed together? 3Na+(aq) + PO43-(aq) - 3Naso (s) + A13+ (aq)
A13+(aq) + PO43-(aq) - AlPO4(s)
35042-(aq) + 3Na+(aq) - Naso,(s)
Al3+ (aq) + PO43-(aq) + 350,2-(aq) - 3 AlPO4(s) + 3Na+(aq)

im pretty sure its b

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
