Thank you, chenbeier for the help.

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

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
