The equation 2BaCO3 -> 2BaO + 2CO2 + O2

  1. The chemical equation above describes the decomposition process of Barium Carbonate (BaCO3) when heated, which will create Barium Oxide (BaO), Carbon Dioxide (CO2), and Oxygen (O2).

  2. Reaction conditions: This reaction occurs when Barium Carbonate (BaCO3) is heated.

  3. Reaction process: Upon heating, BaCO3 decomposes to form BaO and CO2, O2 gases. This decomposition takes place at high temperatures.

  4. Phenomenon occurred: When heated, Barium Carbonate transforms from solid to gases (CO2 and O2) and another solid chemical (BaO). If the reaction is conducted in a closed space, the increase in pressure due to the gas release can be observed.
