A standard textbook on pharmacology notes: "Toxicology is often regarded as the science of poisons or poisoning, but developing a strict definition for poison is
problematic. Explain this statement.

a) the particles of the chair are strongly held together.

the electron configuration that you gave me has 16 electrons ergo it has 16 protons ergo it is the element sulfur.

a electronegativity decreases beacuse the size of nucleus is bigger.

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
