Write a balanced equation for each of the following reactions:
the reaction of solid lithium with nitrogen to form solid lithium nitride.
the reaction between aqueous solutions of cobalt(iii) nitrate and sodium hydroxide to form aqueous sodium nitrate and solid cobalt(iii) hydroxide.
the reaction between solid zinc and aqueous hydrochloric acid in a single replacement reaction.
classify the reactions in (a) and (b).

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
