what type of reaction is when limestone is heated

 Limestone is essentially calcium carbonate and quicklime is otherwise known as calcium oxide. The oxide is produced by heating limestone to around 830 °C, therefore it is decomposition reaction

Word equation:
calcium carbonate -------> calcium oxide + carbon dioxide

Formula equation
CaCO3(s) -------> CaO(s) + CO2(g)

NB: Ca(OH)2 is called slaked lime and is NOT the same as quicklime. Ca(OH)2 is produced by reacting quicklime with water - a process known as slaking

Limestone is calcium carbonate (CaCO3) which when heated to above 840°C decomposes into calcium oxide (CaO) while releasing carbon dioxide (CO2) according to the equation: CaCO3(s) → CaO(s) + CO2(g). it is a decomposition reaction.
