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 Testing for carbon dioxide 12/16/2015 Gas Limewater Limewater turns milky/cloudy Fizz and Chips 2 12/16/2015 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 Burning things 12/16/2015 When something is burned it reacts with oxygen. For example: Magnesium + oxygen Magnesium oxide Carbon + oxygen Carbon dioxide Sulphur + oxygen Sulphur dioxide The Fire Triangle Fire Heat Fuels 12/16/2015 Fuels are substances that can be used to release useful amounts of energy when they burn, e.g. Wood Oil Gas Burning fuels 12/16/2015 When fossil fuels (coal, oil and gas) are burned they produce water and carbon dioxide. We can use this apparatus to show this: In this example the reaction is: Methane + oxygen Carbon dioxide + water
