100 points organize this a$ap

elements and compounds

which ones go in which hurry up plz

c6h12o6, mgci2, naci, o2, pb.

C6H12O6, MgCL2, NaCl are compounds

Pb is element

O2 is neither compound nor element, it's a molecule. But if must need to categorize it, then you can consider it in element, but remember it's not an element

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
