HELP!! When an atom of hydrogen (H) bonds with an atom of chlorine (Cl), what bond is formed to create hydrogen chloride (HCl) and why?
A.
An ionic bond is formed because one valence electron from the nonmetal hydrogen atom is shared with the nonmetal chlorine atom to form a stable octet of electrons.
B.
An ionic bond is formed because one valence electron from the nonmetal hydrogen atom is shared with the nonmetal chlorine atom to form an unstable octet of electrons.
C.
A covalent bond is formed because one valence electron from the nonmetal hydrogen atom is shared with the nonmetal chlorine atom to form a stable octet of electrons.
D.
A covalent bond is formed because one valence electron from the nonmetal hydrogen atom is shared with the nonmetal chlorine atom to form an unstable octet

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 0.42 is that is an option. this question provides no info
