I m confused in this part. I used the mole ratio solution but the answer in Marking scheme is '10800g'. I don't think that's possible becuase, that would be the mass of Octane and to calculate the mass of Carbon dioxide, shouldn't we use the mole ratio?
yes the answer is 10800.....use ur common sense this is the simplest of questions.....if 108 g CO2 is produced every kilometre then obviously 10800 g of carbon will be emitted by the car..

a) i) electrons (cuz it becomes positively charged so that means it lost negative charge)
ii) neutralized cuz the conducting tires provide a medium for charge to flow though. -ve charge from earth neutralizes +ve charge in the plane
iii) cuz presence of any charge will cause sparking in fuel tank

WATERCOOLER is YOURS!!:D
