  1. Simple Chemical Reactions W Richards The Weald School

  2. Testing for hydrogen “POP”

  3. Adding acids to metals If an acid is added to a (fairly reactive) metal the metal will be quickly ________ by the acid. We can see a reaction happening because the mixture _________ and the metal eventually __________. Some metals, like ____, are so unreactive that nothing will happen. Words – gold, corroded, fizzes, disappear

  4. Testing for carbon dioxide Gas Limewater Limewater turns milky/cloudy

  5. Adding acid to carbonates Carbonates are compounds containing carbon and oxygen. When an acid is added to a carbonate the carbonate starts to _______. A gas called ______ _______ is produced. Carbonates used to be used as building materials but aren’t any more because acid rain would eventually ________ the building. Words – dissolve, fizz, carbon dioxide, oxygen

  6. Burning things Magnesium + oxygen Magnesium oxide Carbon + oxygen Carbon dioxide Sulphur + oxygen Sulphur dioxide The Fire Triangle Fire When something is burned it reacts with oxygen. For example: Oxygen Fuel Heat

  7. Fuels Wood Oil Gas Fuels are substances that can be used to release useful amounts of energy when they burn, e.g.
