Write the cell notation for the voltaic cell that incorporates each of the following redox reactions. (Type your answer using the format [NH4] for NH4 , [Mg]2 for Mg2 , and CO2 for CO2.) (a) Al(s) Cr3 (aq) Al3 (aq) Cr(s) (s) | (aq) || (aq) | (s) (b) Cu2 (aq) SO2(g) 2 H2O(l) Cu(s) SO42-(aq) 4 H (aq) Pt | (g) | (aq), H (aq) || (aq) | (s)

the answer is minerals.

since electrons are negative the answer is neagtaive

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
