Zinc and Iron 1 of 13 What name is given to metals which are found in nature and are not combined with other elements? Native metals 2 of 13 What is an ore? A solid metal that can be extracted economically 3 of 13 Write a word equation for the reduction of Zinc Oxide with Carbon Zinc Oxide + Carbon --> Zinc + Carbon Monoxide 4 of 13 What is the most common ore of Iron? Haematite 5 of 13 What is the main impurity of Haematite? Sand 6 of 13 What is the chemical name for limestone? Calcium Carbonate 7 of 13 Write a balanced equation to show how limestone undergoes thermal decomposition in the blast furnace? CaCO3 --> CaO + CO2 8 of 13 What is meant by the term reduction? The removal of Oxygen 9 of 13 How would you stop Iron rusting? Get the Iron chromed, electro-polished, painted, plated with zinc or coated in Polyethane 10 of 13 Explain why heating Zinc Oxide turns to Zinc when heated with Carbon? Carbon is higher up in the reactivity series --> Carbon will displace the Oxygen from Zinc. 11 of 13 What type of reaction has metals reduced and gases oxidised? Redox reactions 12 of 13 Which metal is used for galvanising? Zinc 13 of 13
