Burning

• Burning - Combustion
• Fuel contains chemical energy
• Fuel can burn and react with oxygen in the air
• Fossil fuel:

  1. charcoal
  2. natural gas
  3. coal
• Other fuels:

  1. oil
  2. wood
  3. methane (CH4)
• Combustion releases heat energy and tempurature will increase. This is called an exothermic reaction
• methane + oxygen -> carbon dioxide + water

  CH4 + O2 -> CO2 + H2O
• hydrogen + oxygen -> water

  H2 + O2 -> H2O
• magnesium + oxygen -> magnesium oxide

  Mg + O2 -> MgO
