Adding acids to metals
Words – gold, corroded, fizzes, disappear
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.

Adding acid to carbonatesCarbonates 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

FuelsFuels are substances that can be used to release useful amounts of energy when they burn, e.g.
Oil GasWood

Burning thingsWhen something is burned it reacts with oxygen. For example:
Magnesium + oxygen Magnesium oxide
Carbon + oxygen Carbon dioxide
Sulphur + oxygen Sulphur dioxide

Burning fuelsWhen 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
