SMathew Posted January 28, 2019 Share Posted January 28, 2019 I am doing a science fair project and have a question about the limestone cycle. A typical limestone cycle has 3 parts given below: Cycle - Part 1: CaC03 + Heat -> Ca0 + C02 Cycle – Part 2: Ca0 + H20 -> Ca(OH)2 Cycle – Part 3: Ca(OH)2 + CO2 -> CaC03 + H20 The question is - Can Part 2 of the above cycle be skipped i.e. the part that requires water? And shorted the cycle as: Cycle - Part 1: CaC03 + Heat -> Ca0 + C02 Cycle – Part 2: Ca0 + CO2 -> CaC03 Appreciate help in this. Thanks SMathew Link to comment Share on other sites More sharing options...
chenbeier Posted January 28, 2019 Share Posted January 28, 2019 Theoretical yes, but then you cannot make concrete. Everything has to be mixed with water. Link to comment Share on other sites More sharing options...
SMathew Posted January 29, 2019 Author Share Posted January 29, 2019 Thank you for the reply. For my science project, I plan to use limestone to capture CO2 from the air. If possible, I would like to avoid using water. Can this be achieved? Thanks SMathew Link to comment Share on other sites More sharing options...
chenbeier Posted January 29, 2019 Share Posted January 29, 2019 Should be possible, but you have to find a way to get a large surface. Link to comment Share on other sites More sharing options...
