Question 15

Environmental Pollution

The air around a petroleum refinery is most likely to contain

  1. A.CO2, SO3 and N2O
  2. B.CO2, CO and N2O
  3. C.SO2, CO and NO2
  4. D.PH3, H2O and CO2
Show the answer and explanation

Answer: C (SO2, CO and NO2)

Explanation

Crude oil contains sulphur, and burning fuel in refineries forms carbon monoxide and nitrogen oxides, so SO2, CO and NO2 are the typical pollutants.
