The equation 2MnCO3 -> 2MnO2 + 2CO2 + O2

  1. Detailed information on the equation 2MnCO3 -> 2MnO2 + 2CO2 + O2 ->

    • This is a chemical equation depicting the decomposition process of manganese carbonate (MnCO3). When heated, it decomposes into manganese dioxide (MnO2), carbon dioxide (CO2), and oxygen (O2).

  2. Reaction conditions

    • The main condition for the reaction to occur is the heating of manganese carbonate.

  3. Reaction process

    • When heated, the molecules of manganese carbonate quickly decompose, exchanging atoms with each other to form manganese dioxide, carbon dioxide, and oxygen.

  4. Occurring phenomena

    • When the reaction takes place, you will observe changes in color and shape of the reactant. Manganese carbonate usually has a light pink or white color, but after the reaction, manganese dioxide will be brown-black. In addition, you will also see the gases carbon dioxide and oxygen being released.
