Approximately 1 ml of two clear, colorless solutions-0.1 m ba(no3)2and 0.1 m na2so4- were combined. upon mixing, a thick, milky white precipitate formed. after centrifugation, the solution above the precipitate was found to be clear and colorless. based on these observations, determine if a reaction occurred. if so, write the balanced chemical equation and net ionic equation for the reaction.

2. predict if a reaction would occur when solutions of 0.1 m al(no3)2and 0.1 m ki are combined. explain your reasoning, and, if you predict a reaction will occur, include the net ionic equation for the reaction.

3. when a solution of 0.1 m mg(no3)2was mixed with a limited amount of aqueous ammonia, a light white, wispy solid was observed, indicating a reaction took place. write the net ionic equation for this reaction.

the correct answer would be d. hope this !

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
