A common experiment in introductory chemistry courses involves heating a weighed mixture of sodium chlorate, NaClO3, and sodium chloride. Sodium chlorate decomposes when heated, producing sodium chloride and evolving oxygen gas. Write the word equation, symbolic equation and balance the equation.

the answers would be

the first one and the second one

it forms an anion that has a larger radius. anions have a negative charge and are larger than the original atom.

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
