What is reduction with carbon?Show answer
When a metal oxide is heated with carbon, the carbon takes the oxygen away from the metal. Removing oxygen is called reduction, so the metal oxide is reduced to the metal. Carbon can only do this for metals less reactive than itself.
What is extraction of iron in the blast furnace?Show answer
Iron is extracted from iron oxide in a blast furnace:
What is q1?Show answer
State the method used to extract a metal that is less reactive than carbon, such as zinc. [1 mark]
What is q2?Show answer
Name the two conditions needed for iron to rust, and one way to prevent it. [2 marks]
What is q3?Show answer
Explain why aluminium cannot be extracted by heating its oxide with carbon. [2 marks]
