GCSE Chemistry - Air Pollution #70

The video explains the combustion of fossil fuels, highlighting the difference between complete and incomplete combustion. It discusses the pollutants produced, such as particulates, carbon monoxide, sulphur dioxide, and nitrogen oxides, and their harmful effects on health and the environment. The video also covers the formation of acid rain and its impact on infrastructure and plant life.

What are the primary products of complete combustion of hydrocarbons?

• Sulfur dioxide and nitrogen oxides

• Soot and carbon monoxide

• Carbon dioxide and water

• Carbon monoxide and water

What is a major health risk associated with inhaling particulates?

• Respiratory problems

• Enhanced energy levels

• Improved lung function

• Increased oxygen transport

Why is carbon monoxide particularly dangerous to humans?

• It enhances oxygen binding in the blood

• It binds to hemoglobin, reducing oxygen transport

• It is easily detectable by smell

• It causes immediate skin irritation

How are nitrogen oxides typically formed during combustion?

• By burning pure hydrocarbons

• Through low-temperature reactions

• From impurities in the fuel

• When nitrogen and oxygen react at high temperatures

What environmental issue is caused by sulfur dioxide and nitrogen oxides mixing with clouds?

• Increased plant growth

• Ozone layer depletion

• Acid rain

• Global warming
