How many kilojoules of energy are released when enough methane gas, CHa reacts with oxygen gas, O2 to form 0.66 moles of water, H20? (Show your work or explain your
answer)
CH4 + 202 → CO2 + 2H20 + 890.0 kJ

3

explanation:

1.43 x 10^-11 j the guy commented the awnser just making sure u see it .

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
