Chose the statements that are TRUE from the list below Group of answer choices Lactate is created by our muscles during anaerobic glycolysis, it reacts with water to form lactic acid. We add calcium carbonate to lakes after acid rain because the calcium ion is basic and will react with the acid. Ions exist alone in nature Fluorine anion is a weak base because hydrofluoric acid is a weak acid If Lake A has a limestone base and Lake B has a granite base, after each receive the same acid rain fall, Lake B will be more acidic than Lake A All salts are either acidic or basic after being dissolved in water.

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
