|What are the uses of limestone?
|Can be used to make cement for concrete
|What is limestone mainly made out of?
|What happens when we heat limestone?
|Calcium carbonate breaks down to make calcium oxide and carbon dioxide, this reaction is called thermal decomposition
|What do carbonates produce when reacted with dilute acid?
|A salt, carbon dioxide and water
|What is the test for carbon dioxide gas?
|Use limewater, if it turns cloudy then carbon dioxide is present
|When water is added to calcium oxide, what does it become?
|What does an alkaline do to acids?
|What is the limestone reaction cycle?
|How is mortar made?
|By mixing sand, cement and water together
|How is cement made?
|By mixing limestone and clay in a kiln
|How is concrete made?
|By mixing sand and water with aggregate (crushed rocks or small stones)
