Calcium Carbonate or CaCO3 2 of 17 When limestone is heated what products are made? Calcium Oxide and Carbon Dioxide 3 of 17 Calcium Oxide reacts with water to produce what? Calcium Hydroxide 4 of 17 Name three other carbonates that decompose in the same way as CaCO3 Sodium Carbonate, Magnesium Carbonate, Copper Carbonate 5 of 17 Why do some people not agree with quarrying limestone? Air pollution (dust), visual pollution, damage to habitats of animals, traffic due to lorries 6 of 17 What is a disadvantage of using Limestone? It is suseptable to damage via acid rain as it is reactive 7 of 17 How is concrete made? Cement, sand and aggregate 8 of 17 Advantages of quarrying limestone Valuable and cheap builiding material, neutralise acidic soil, provide local jobs 9 of 17 What is the chemical name for Slaked Lime Calcium Hydroxide 10 of 17 Calcium Oxide is also known as Quicklime 11 of 17 How do you produce Calcium Oxide from Calcium Carbonate? By heating it 12 of 17 Metal carbonates break down when heated, what is this process called? Thermal Decomposition 13 of 17 What do we get when we dissolve Calcium Hydroxide in water? Limewater / Calcium Hydroxide solution 14 of 17 How do we test for Carbon Dioxide? Bubble gas through limewater and if it turns cloudy there is CO2 15 of 17 What is the limestone Cycle?
