2. The chemical formula for limestone is:

  • CaCO3
  • caco3
  • CACO3
  • CaCo3
  • caCo3

3. We thermally decompose Calcium Carbonate to get:

  • Calcium Oxide + Oxygen
  • Calcium Oxide + Carbon Dioxide
  • Carbon Dioxide + quick lime
  • Calcium Dioxide

4. Check the correct equation

  • CaO + H2O = Ca(OH)2
  • 2CaO + 4H2O = 2Ca(OH)2
  • Ca(OH)2 + H2O = CaO
  • Ca(OH)2 + H2O = CaCO3

5. How do we make limestone into Cement?

  • Heat it in a kiln with water and sand
  • Heat it in a kiln with powdered clay
  • Mix it with water and sand
  • Heat it in a kiln with sand and clay

Good quiz, really helpful!

But for the third question, Quicklime and Calcium Oxide are the same thing so you could tick either and they would be correct :/

Thanks for the quiz tho :P
