Mix crushed limestone, clay and sand 2 of 15 How do you make concrete? Mix crushed limestone, clay, sand and aggregate 3 of 15 What are the advantages of quarrying? Creates a valuable material and increased employment 4 of 15 What are the disadvantages of quarrying? Noise, dust, pollution and spoils landscape. 5 of 15 How do you perform the process of thermal decomposition and what is the result? Heat calcium carbonate which creates calcium oxide and carbon dioxide is also given off. 6 of 15 what is the word and symbol equation for thermal decomposition? Calcium Carbonate--->Calcium oxide+Carbon dioxide 7 of 15 What is the chemical name for limestone? Calcium carbonate 8 of 15 What happens of you add water to the result of thermal decomposition? It becomes solid calcium hydroxide 9 of 15 What is the word and symbol equation for making solid calcium hydroxide? Calcium oxide+water--->solid calcium hydroxide. CaO+H2O--->Ca(OH)2 10 of 15 What happens if you add water to solid calcium hydroxide? It becomes calcium hydroxide solution 11 of 15 What is the chemical name for calcium hydroxide solution? limewater. 12 of 15 How is the test for carbon dioxide performed? Blow bubbles in to calcium hydroxide solution and if it goes cloudy it means carbon dioxide is present. 13 of 15 What is the word and symbol equation for test for carbon dioxide? calcium hydroxide solution+carbon dioxide--->calcium carbonate+water. Ca(OH)2+CO2--->CaCO3+H2O 14 of 15 Carbonates at the top of group 1 in the periodic table are difficult to_________and therefore require____that is higher than in a______ ______ decompose, heat, bunsen burner. 15 of 15
