The chemical equation CaCO3 + CaCl2 -> 2CaCl2 + CO2

Detailed information about the equation CaCO₃ + CaCl₂ -> 2CaCl₂ + CO₂
The equation represents the chemical reaction process between calcium carbonate (CaCO₃) and calcium chloride (CaCl₂) to produce calcium chloride (CaCl₂) and carbon dioxide gas (CO₂).
However, this equation is not balanced because it shows an increase in the amount of CaCl₂ after the reaction with no additional source. The correct balanced equation would be CaCO₃ -> CaO + CO₂ -> , where calcium carbonate is thermally decomposed into calcium oxide and carbon dioxide gas.

Reaction conditions
The thermal decomposition reaction of CaCO₃ requires a sufficiently high temperature, usually around 800-900 degrees Celsius.

Reaction process
When calcium carbonate is heated at a high temperature, it decomposes into calcium oxide and carbon dioxide gas. This process is called thermal decomposition.

Phenomena occurring
When the reaction occurs, you will see gas rising – this is the carbon dioxide gas produced during the reaction. Calcium oxide will remain in a solid form.
Note: Always adhere to safety rules when carrying out chemical experiments.
