In the buffer solution CH3COSH(aq) =H30faq) + CH3CO2(aq) OA) CH3CO H is a base, and H3O+ is its conjugate acid.
B) H3O+ is an acid, and CH3CO2 - is its conjugate base.
OC) Hz0+ is an acid, and CH3CO2H is its conjugate base.
D) CH2CO2H is an acid, and CH3CO2 is its conjugate base.

a boiling water reactor does not boil the water. a pressurized water reactor boils the water faster. a pressurized water reactor is heated directly by the core. a pressurized water reactor does not use fission.

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
