The equation CaO + CO2 -> CaCO3

  1. Detailed information about the equation CaO + CO2 -> CaCO3:

    • In this equation, calcium oxide (CaO) interacts with carbon dioxide (CO2) to create calcium carbonate (CaCO3). This equation ensures atomic conservation: each element before and after the reaction has the same number of atoms.

  2. Reaction conditions:

    • The reaction occurs under normal temperature and pressure conditions.

  3. Reaction process:

    • CaO and CO2 react with each other to create CaCO3. This reaction is a type of ion exchange reaction between a base and a strong acid, resulting in the formation of salt and water.

  4. Phenomena occurring:

    • When CO2 is passed through CaO, the observed phenomenon is the gradual dissolution of the CaO powder to form CaCO3.
