The correct answer is C: smog. Smog is a type of air pollution that is caused by a mixture of smoke and fog. It's often found in cities that use coal for electricity, because coal combustion releases a lot of pollutants into the air. These pollutants can mix with fog and create smog.
The reason option D is incorrect is because sulphur(iv)oxide is not the main pollutant in cities that use coal for electricity. While sulphur(iv)oxide is a byproduct of coal combustion, it's not the main pollutant. The main pollutants are actually particulate matter and nitrogen oxides. So option D isn't the best answer.
Myschool please correct this ,the correct answer is Smog it was clearly stated in Newschool chemistry
Smog is a general term for smoky fog which results from trapped pollutants. It is not a pollutant itself but can result from other appropriate ones (like Sulphur (iv) oxide)
In an exam context, sulfur(IV) oxide (SO2) is generally the better answer when comparing it with smog for pollutants from coal. While smog is a mixture of pollutants, SO2 is a direct and primary pollutant released when coal is burned, and its presence is a major factor in forming smog.
Between C (Smog) and D (Sulphur(IV)oxide), the correct answer is D (Sulphur(IV)oxide).
Sulphur(IV)oxide (SO2) is a pollutant commonly associated with the combustion of coal, which is used to generate electricity...
