From an ethical standpoint, which best describes why new biotechnology products should be tested extensively before they are allowed to be used? There can be unintended consequences to many new biotechnology products. Many new products end up being more expensive than they appear to be. Biotechnology products tend to stop working after a few years. There are usually no benefits to the products of biotechnology.

answer: i dont know the answer but this might

explanation:

l

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
