To give an example of decomposition reaction in everyday life

General Information :

Decomposition Reaction refers to the type of reaction in which a compound on supply to energy like heat, or light, breaks to form two or more chemical products.

One example of decomposition reaction that is used is :

  CaCO₃     +      ΔHeat   →    CaO      +      CO₂↑

Calcium carbonate                Calciumoxide    Carbondioxide gas

The calcium carbonate ore (called calcite/limestone) is heated at high temperatures to obtain calcium oxide which is an essential constituent of cement. Cement has many uses, mostly for building and as an adhesive.
