When 1.37 grams of mixture G consisting of metal M and Al react with dd HCl surplus is obtained dd and 1,232 liters of H2 (VNDtc). On the other hand, if 1.37 grams of mixture G are given,
When used with heated chlorine gas, the amount of chlorine needed is just enough to work with the mixture

G is exactly equal to the amount of chlorine prepared by adding 3.792 grams of KMnO4 to
used with excess concentrated HCl.

answer:

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

ans is no, the data set cannot be plotted as a single circle graph

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
