6.4 x 10^-7 = [CO]^2[O2]/ [CO2}^2 = ( 2.0 x 10^-3)^2 ( 1.0 x 10^-3)/ [CO2]^2 =
=4.0 x 10^-9 / [CO2]^2 

[CO]= sq.rt ( 4.0 x 10^-9)/ 6.4 x 10^-7=7.9 x 10^-2 M 

2.6 x 10^-3 = [I]^2 / [I2] = [I]^2 / 0.95 
[I]= sq.rt ( 2.6 x 10^-3 x 0.95)=5.0 x 10^-2 M 

Ksp = [Ba2+][CO32-] = ( 1.1 x 10^-4)^2=1.2 x 10^-8

Describe and explain how petrol is separated from the mixture of hydrocarbons in crude oil?

leonid [27]

It's an exciting and interesting process but those 5 points aren't worth a decent answer. The whole process is called fractioned distillation where different temperatures are reached, transforming the crude oil in gas. After being hit by a cold source it colds becoming different hydrocarbons depending on the temperatures.
