Limestone and Building Materials 0.0 / 5 ? ChemistryLimestoneGCSEAQA Created by: Megan xCreated on: 07-06-14 16:24 What is Limestone? Is a sedimentary rock that consists of mainly calcium carbonate. It is cheap, easy to obtain and has many uses. 1 of 6 What can Limestone be used for after being quarried? Limestone can be quarried and cut into blocks to build walls of house, in regions where limestone is plentiful. 2 of 6 What happens when Calcium Carbonate is heated? When Calcium Carbonate is heated it decomposes to make Calcium Oxide and Carbon dioxide. 3 of 6 What is this reaction called? Thermal Decomposition. 4 of 6 Other metal carbonates undergo thermal decomposition on heating. What do they produce. They also produce a meatl oxide and carbon dioxide. For example Magnesium Carbonate is heated to produce magnesium oxide and carbon dioxide. 5 of 6 Can Group 1 metal carbonates undergo thermal decomposition? Yes, but some group 1 metals require higher temperatures than a bunsen burner can provide in order to undergo thermal decomposition. 6 of 6
