Burning fossil fuels

• Carbon monoxide (CO) can be produced when there isn't enough oxygen present during combustion.
• The combustion reaction is the burning of hydrocarbons to produce carbon dioxide, water vapor, and energy.
• Carbon dioxide is the main greenhouse gas that contributes to global warming.
• Coal also contains carbon, sulphur and other particles
• How is sulphuric acid formed


  When sulphur is burnt and the vapour mixes with the water in rain clouds
• Effects of sulphur dioxide


  Acid rain

  Sulphur dioxide can also cause global dimming. This is when sunlight is absorbed by particles in the atmosphere
• Sulphuric acid causes damage to buildings, plants and animals
• Pollution


  CO2, water vapour, and CO are all produced by the burning of fossil fuels

  CO is hard to detect due to being colourless and odourless
• More on acid rain


  Acid rain is also caused by nitrogen dioxide and can damage trees and building and causes respiratory problems in humans and animals
• What are particulates


  Unburned fossil fuels

  They can make buildings dirty and can worsen breathing difficulties and cause global dimming
• Hydrogen as a fuel


  Used in rocket engines and reacts with oxygen in an exothermic reaction
