Question
Which of the following is NOT produced by burning coal?a.Ozoneb.SO2c.NOxd.CO2
Solution
The answer is a. Ozone.
Here's why:
a. Ozone - Ozone is not a direct byproduct of burning coal. It is a secondary pollutant formed when nitrogen oxides (NOx) and volatile organic compounds (VOCs) react in the presence of sunlight.
b. SO2 - Sulfur dioxide (SO2) is a byproduct of burning coal, especially coal that contains sulfur.
c. NOx - Nitrogen oxides (NOx) are also byproducts of burning coal. They are formed when the nitrogen in the air reacts with oxygen under the high temperature and pressure conditions inside a coal-burning power plant.
d. CO2 - Carbon dioxide (CO2) is a major byproduct of burning coal. It is formed when the carbon in coal reacts with oxygen in the air.
