Calcium oxide
When limestone is heated, it undergoes thermal decomposition to produce calcium oxide (quicklime) and carbon dioxide gas. This reaction is represented by the equation: CaCO3 (s) -> CaO (s) + CO2 (g).
Calcium oxide
The gas is Carbon dioxide, formed by the decomposition of Calcium carbonate it the Marble or Limestone
Carbon Dioxide (CO2)
Carbon dioxide is released.
When heated, limestone forms two different things. It forms both calcium oxide and carbon dioxide. This occurs because limestone is made up of calcium carbonate.
When limestone (calcium carbonate) is heated, it undergoes thermal decomposition to produce calcium oxide (quicklime) and carbon dioxide gas. The chemical equation for this reaction is: CaCO3 (s) → CaO (s) + CO2 (g).
it is the decomposition reaction, CaCO3 = CaO + CO2
Carbon dioxide.
When limestone (calcium carbonate) is heated strongly, it undergoes thermal decomposition to produce quicklime (calcium oxide) and carbon dioxide gas. The chemical reaction is represented as: CaCO₃ (s) → CaO (s) + CO₂ (g). This process is known as calcination and is commonly used in various industrial applications, including the production of cement and lime.
carbon dioxide calcium oxide (quicklime) CaCO3 > CaO + CO2
When calcium carbonate (limestone, CaCO3) breaks down, carbon dioxide (CO2, gas) and calcium oxide (CO, solid) are formed
