C1 3.1 Extracting Metals 0.0 / 5 ? ChemistryExtracting metals /The reactivity seriesGCSEAQA Created by: kieraharding1Created on: 15-12-16 17:11 Where are metals found? In the earths crust. 1 of 18 What are metals often combined with? Other chemical elements. 2 of 18 What must we do to a metal compound before we use it? Separate it from its compounds. 3 of 18 What is an ore? A solid material from which a metal or valuable mineral can be extracted profitably. 4 of 18 What does extracting a metal depend on? How easy it is to extract it from its ore and How much metal the ore contains. 5 of 18 Name two metals that are found in the earth pure. Gold and Silver 6 of 18 Why are gold and silver found as themselves (pure) in the earth? Because they are so unreactive. 7 of 18 What do we say nonreactive metals are found in? Native State 8 of 18 What does the way we extract a metal depend on? Its place in the reactivity series. 9 of 18 Between a more reactive metal and a less reactive metal, which will displace the other? The more reactive will displace the less reactive from their oxides. 10 of 18 A metal cannot be extracted from its ore using carbon. Where is this metal in the reactivity series? Above carbon. 11 of 18 What are metals called when combined with oxygen? Metal Oxides. 12 of 18 Metals that are less reactive than carbon can be extracted by... carbon. 13 of 18 Metals more reactive than carbon can be extracted by... Electrolysis. 14 of 18 What is the removal of oxygen from a compound called? A reduction reaction. 15 of 18 Write a word equation for the reduction reaction of lead oxide and carbon. lead oxide + carbon --> lead + carbon dioxide. 16 of 18 What metal is at the top of the reactivity series? Potassium 17 of 18 What metal is at the bottom of the reactivity series? Platinum 18 of 18
