Air pollution

• What do burning fossil fuels produce?

  Carbon dioxide and water
• When does complete combustion occur?

  When pure hydrocarbons burn with plenty of oxygen
• What is produced during incomplete combustion?

  Carbon monoxide and particulates
• What are particulates in the context of combustion?

  Solid particles of carbon called soot
• What are the two main problems associated with particulates?

  They damage lungs and cause global dimming
• How do particulates affect sunlight?

  They form smog that reflects sunlight back
• Why is carbon monoxide particularly dangerous?

  It binds to hemoglobin, reducing oxygen transport
• What are the symptoms of carbon monoxide poisoning?

  Fainting, coma, and death
• What makes carbon monoxide hard to detect?

  It is colorless and odorless
• How is sulfur dioxide produced during combustion?

  Sulfur in hydrocarbons gets oxidized
• How are nitrogen oxides formed?

  Nitrogen and oxygen react at high temperatures
• Why do internal combustion engines produce nitrogen oxides?

  They reach high temperatures for reactions
• What are the health effects of breathing in sulfur dioxide and nitrogen oxides?

  They can damage lungs and cause respiratory problems
• What happens when sulfur dioxide and nitrogen oxides mix with clouds?

  They form dilute sulfuric and nitric acids
• What is acid rain and how does it form?

  It forms from acids in clouds falling as rain
• What are the effects of acid rain on the environment?

  It damages buildings, statues, and plants
• How does acid rain affect soil and plants?

  It makes soil more acidic, hindering growth
