Carbon dioxide and water are produced when pentane (C5H12) reacts with oxygen. What is the balanced equation for this reaction?
O C5H12(g) + O2(g) - CO2(g) + H2O(g)
O C5H12(g) + O2(g) - 5CO2(g) + H2O(9)
O C5H12(g) +8O2(g) - 5CO2(g) + 6H2O(g)
05C02(g) + 6H2O(g) - C5H12(g) + 802(9)
C5H129) +5029) - 5CO2(g) + 6H2(9)
O CH2(g) +O2(g) - CO2(g) + H2(g)

i don't know people like to fight everywhere rip.

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
