Earthquakes and volcanoes 4 of 16 What are properties of aluminium? Low density and does not corrode due to its protective oxide layer. 5 of 16 What are alloys? Mixtures containing at least one metal. 6 of 16 What is thermal decomposition? Reaction where one substances breaks down when heated to give at least two new substances. 7 of 16 What type of rock is limestone?

Metamorphic rock, formed when limestone is changed by heat and pressure, baked. 9 of 16 What type of rock is granite? Igneous rock, interlocking crystals, formed when magma cools. 10 of 16 Is impure copper anode or cathode? Impure copper is anode and pure copper is cathode 11 of 16 What happens to the anode and cathode in electrolysis? Anode loses mass as the copper dissolves and the cathode gains mass. 12 of 16 What is the word equation for rusting? iron + oxygen + water == hydrated iron(III) oxide 13 of 16 What are advantages of recycling materials from old cars? Less mining saves finite resources, less crude oil used, less waste, fewer toxic materials. 14 of 16 Whats the main disadvantage of recycling materials from old cars? Difficult and expensive to separate materials. 15 of 16 What is the Haber process? A process which makes fertilisers.
