Metals 0.0 / 5 ? ChemistryRocks, ores, metals and alloysGCSEAQA Created by: EdithCreated on: 22-03-16 10:23 What is the reactivity series? It helps with displacement reaction. If the metal is below carbon, you use carbon to extract metals or if it is above you use electrolysis. 1 of 13 How do you extract aluminium? You would use electrolysis to extract aluminium. 2 of 13 How do you extracts iron? You would use carbon to extract iron 3 of 13 What is reduction? Reduction is the removal of oxygen from a compound 4 of 13 What is an ore? An ore is a rock containing enough metal to make it economic to extract the metal 5 of 13 What is a native state? Unreactive metals found as elements in nature 6 of 13 What materials meet in a blast furnace? Cinter, iron ore, coke and limestone is added later 7 of 13 What are the properties of a blast furnace? Gets very hot, full of carbon, iron oxide inside, produce co2, reduces and oxidises 8 of 13 Wha does a blast furnace do? Heats cinter, iron ore, coke and limestone at 2200 degrees and reduces and oxidises it. 9 of 13 What is a metal? Metal ions are delocalised electrons, they are arranged in layers, delocalised electrons enable conduction of heat and electrons 10 of 13 What is an alloy? Mixture of metals, different sized atoms prevent sliding, harder than pure metals 11 of 13 How is copper extracted? Usually extracted by heat but can be treated by sulfuric acid when we get the solution copper sulfate. 12 of 13 How can we obtain copper metal from extraction? We can obtain metal by adding iron metal or by passing electricity through the solution. 13 of 13
