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 incomplete combustion?

  Burning with insufficient oxygen
• What pollutants are produced from burning fossil fuels?

  Carbon monoxide, particulates, sulfur dioxide, nitrogen oxides
• What are particulates?

  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 can severe carbon monoxide poisoning lead to?

  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 high temperatures lead to nitrogen oxides formation?

  They allow nitrogen and oxygen to combine
• What happens when sulfur dioxide and nitrogen oxides mix with clouds?

  They form dilute sulfuric and nitric acids
• What are the effects of acid rain?

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

  It makes the soil more acidic
• What is complete combustion and its products?

  • Complete combustion occurs with sufficient oxygen
  • Products are water and carbon dioxide
• What are the health effects of inhaling particulates?

  • Can damage lungs
  • Leads to respiratory problems
• What are the environmental impacts of carbon monoxide?


  • Reduces oxygen transport in blood
  • Can lead to severe health issues
• What are the sources of sulfur dioxide and nitrogen oxides?

  • Sulfur dioxide from burning sulfur-containing hydrocarbons
  • Nitrogen oxides from high-temperature reactions in engines
• What are the consequences of acid rain on buildings and plants?

  • Damages buildings and statues
  • Harms plants by increasing soil acidity
• why is suffer dioxide ironmental issue

  
  

  Produced in combustion of fossils fuels that contain sulfur impurities

  which causes acid rain

  damages building, plant, lakes
• Nitrogen dioxide

  Nitrogen oxidised in engines due to high pressure and temperature
• How acid rain comes about

  Sulfure dioxide and nitrogen oxide mix with clouds

  Forming dilute acids

  Falls as acid rain
