39. Give the net ionic equation for the reaction (if any) that occurs when aqueous solutions of Na2CO3 and
HCI are mixed.
A) 2 H+(aq) + CO32-(aq) H2CO3(s)
B) 2 Na+ (aq) + CO32-(aq) + 2 H+(aq) + 2 Cl-(aq) –
H2CO3(s) + 2 NaCl(aq)
C) 2 H+(aq) + CO32-(aq) H20(1) + CO2(g)
D) 2 Na+(aq) + CO32-(aq) + 2 H+(aq) + 2 Cl-(aq)
H2CO3(s) + 2 Na+(aq) + 2 Cl(aq)
E) No reaction occurs.

the answer is c

tell me if wrong

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
