6. For the equation SnO2 + 2H2 Sn + 2H20, tin (IV) oxide reacts with excess hydrogen to produce tin and water. What is the limiting reactant?

in the analysis of systems that involve fluid flow, we frequently encounter the combination of properties u and pv.

answer:

technetium is the most reactive. this is followed by silver. the least reactive out of these three elements is strontium.

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
