27. the diagram shows an electrolytic cell in
which the electrodes are tin and copper.

solution
when the switch is closed, what will happen
to the two electrodes?
(1) b will dissolve and a will become coated
with tin.
(2) a will dissolve and a rbeit sonfed
with tin.
(3) b will dissolve and a will become coated
with copper.
(4) a will dissolve and b will become coated
with copper

wher is the rest of the question

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

the answer is yes

it has kinetic energy

reason

an object has kinetic energy when you stop the force carrying it, the object will stay in motion.

hope this contact me for more questions if you'd like: )
