Considere as equações. : i- al2o3+hcl> alcl3+h2o. ii-so2+naoh> na2so3+h2o. iii- bao4+hno> ba (no3)2+h2o+o2 a sequência correta dos coeficientes dos reagentes e produto necessários para o balanceamento estequiométrico dessa equação é: i. a) 6,3,3,2. b)1,6,2,3 c)1,3,3,2 d)6,1,2,3 e)1,6,2,3 ii. a)1,2,1,1 b)2,1,1,1, c)2,1,2,2 d)2,1,2,2 e)1,2,1,1 iii a)2,1,2,2,2 b)1,1,2,1,1 c)1,2,1,1,1 d)2,1,2,2,2 e)1,2,1,1,1

it would be d. henry moseley

hope this !

and sorry if i'm late. have a good rest of your day! : d

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

it is reliable if two scientists recorded it
