The equation 2CaO -> 2Ca + O2

  1. Detailed information about the equation 2CaO -> 2Ca + O2 -> :

    The above chemical equation represents the decomposition reaction of calcium oxide (CaO) into calcium (Ca) and oxygen (O2). In this reaction, one molecule of calcium oxide decomposes into one atom of calcium and one atom of oxygen.

  2. Reaction conditions:

    This is an endothermic decomposition reaction, meaning the reaction only takes place at high temperatures.

  3. Reaction Process:

    When the temperature is high enough, the CaO molecules will rapidly decompose, releasing calcium and oxygen. This process will continue until there is no more calcium oxide or when the temperature falls below the necessary level for the reaction to occur.

  4. Visible Phenomena:

    When the reaction takes place, you will see the amount of solid substance (calcium oxide) decrease. At the same time, you may see oxygen gas being generated. The calcium produced in this process may not be easily visible as it may still be in a molten state.
