ChemistryMetals, metal ores and alloysGCSEAQA Created by: michi_99xCreated on: 05-03-16 16:43 What are the properties of a metal? -Sonorous , ductile, solids, magnetic, good conductors of heat and electricity and malleable. 1 of 38 Where are metals found? Earth's Crust 2 of 38 What is a metal ore? A rock that contains a lot of a type of metal in it 3 of 38 What is displacement? A more reactive metal would displace the less reactive 4 of 38 What is carbon more reactive than? Copper, lead, iron and zinc 5 of 38 What is the process of smelting? 1) Roasting 2)Reduction 3) Fluxes 6 of 38 What are the uses of iron? Watch, cutlery, Earth's core 7 of 38 What is the iron's ore? Haematite 8 of 38 What raw materials are needed to extract iron? Carbon- coke, limestone and air. 9 of 38 What happens when they combine together? Carbon and oxygen is produced- carbon monoxide 10 of 38 What can form when iron oxide and carbon monoxide react? Carbon dioxide and molten iron 11 of 38 How is **** made? When hot air is added to the furnace 12 of 38 What is an alloy? Two metals or more that combine together 13 of 38 Why are alloys made? To make metals harder 14 of 38 What are smart alloys? An alloy that remembers their shape 15 of 38 How are alloys different to metals? They are irregular, more spaced and the layers cannot slide over eachother 16 of 38 How is iron extracted? Through a blast furnace ( cast iron) 17 of 38 What does it contain? 96% impure iron and 4% carbon and other impurities 18 of 38 What is the ore of copper? Chalcopyrite 19 of 38 What is electrolysis? Running an electric current through an electrolyte. 20 of 38 Electrolyte is... Solution containing ions that conduct electricity 21 of 38 Where does the impure copper go? To the anode 22 of 38 Where does the pure copper go? To cathode 23 of 38 What happens to the anode? It starts to dissolve 24 of 38 What happens to the cathode? It is coated with copper, gets bigger 25 of 38 What are aluminium's properties? low density, strong,good electrical and heat conductor 26 of 38 What is aluminium used for? Overhead power lines, aircraft bodies 27 of 38 What are titanium's properties? heavy weight, resistant to corrosion, high mp 28 of 38 What is titanium used for? Rockets and hip replacements 29 of 38 Remember that Panic means Positive Anode Negative Is Cathode 30 of 38 What is aluminium's ore? Bauxite 31 of 38 What about titanium's ore? Rutile 32 of 38 How would you extract titanium? first convert it to tetrachloride, react with magnesium 33 of 38 What is open-cast mining? It is when you move mountains which leaves holes and creates mountains of waste rock elsewhere. 34 of 38 What are finite resources? When something runs out but cannot be replaced 35 of 38 What is bioleaching? Uses less electricity and produces no waste gases. It's when bacteria grow on ores and the solution is extracted through electrolysis or displacement 36 of 38 What is phytomining? Burning plants that leave ash and contain copper. It's extracted by electrolysis. 37 of 38 What is a catalytic converter? Carbon monoxide -> Carbon Dioxide 38 of 38
