The equation 2PbCO3 -> 2PbO + 2CO2 + 2O2.

  1. Detailed information about the equation 2PbCO3 -> 2PbO + 2CO2 + 2O2 -> :

    • This is a chemical equation describing the decomposition reaction of lead carbonate (PbCO3) into lead oxide (PbO), carbon dioxide (CO2) and oxygen (O2). This reaction belongs to the category of decomposition reactions.

  2. Reaction conditions:

    • This reaction occurs when lead carbonate is heated.

  3. Reaction process:

    • When heated, PbCO3 molecules decompose into PbO, CO2 and O2 molecules. Lead carbonate (PbCO3), under the effect of heat, decomposes into lead oxide (PbO), carbon dioxide gas (CO2) and oxygen gas (O2).

  4. Phenomena occurring:

    • When heated, lead carbonate (PbCO3) changes from solid to gas form, generating carbon dioxide gas (CO2) and oxygen gas (O2). The phenomenon of changing from solid to gas can be observed by seeing the disappearance of solid lead carbonate and the appearance of gas bubbles during the reaction. Lead oxide (PbO) remains in solid form after the reaction.
