Presentation Transcript

  1. Limestone Limestone Learning Objectives: What is Thermal Decomposition? The reaction of quicklime with water know the balanced equation for the reaction of limewater and carbon dioxide

  2. Click on the girl for the starter questions Thermal Decomposition Limestone Click here for Task Why is a Zombie different to a normal person? What should happen to the human body when life is no longer present? Do Chemicals decompose?

  3. How do you think the following will decompose? Limestone Calcium Carbonate CaCO3 Click on me to reveal answer CaO + CO2 Copper Carbonate CuCO3 Click on me to reveal answer CuO + CO2 Sodium Carbonate Na2CO3 Click on me to reveal answer Na2O + CO2

  4. Balancing Acts! Limestone

  5. Limestone Mg C O O O Mg O C O O

  6. Circle of Life... Limestone WHOA!! Didn’t see you watching, that’s embarrassing! I was wondering about the Life of a star and I do not mean David Beckham! I wonder if chemicals can go through a ‘Circle of Life’?

  7. Click on the heading at the bottom then Click on the + and the arrows to reveal the answers Limestone and the “Circle of Life...” Limestone Click here for Instructions Carbon Dioxide Calcium Oxide Water Thermal Decomposition Calcium Hydroxide Calcium Carbonate + Water Filter then add Water Limewater Ca(OH)2 Carbon dioxide

  8. Limestone Click here to reveal answer Carbon dioxide Limewater Calcium Carbonate + Water Complete the word equation above Ext: Can you write a formula equation for the above reaction?
