Double Decomposition Reaction.
Here Caco3 Is Heated At High Temperature At About 382.6Kj And Decompose Into Two Compounds I.e. Cao (Slaked Lime ) and Co2 (Carbon Dioxide)
Hope This Works Out

Here,Caco3 is heated at high temperature about 382.6Kj.
Formation of Calcium
Hydroxide:Reaction between quick lime (Calcium oxide, CaO) and water is a combination reaction.
In this reaction, quick lime reacts with water to form slaked lime (calcium hydroxide, Ca(OH)2).
The reaction between quick lime and water is highly vigorous as well as exothermic.Combustion Reactions: Combustion of coal and combustion of hydrogen are examples of combination reactions.
Coal burns in air to form carbon dioxide gas.Hydrogen burns in the presence of oxygen to form water in the form of steam. Upon cooling, it becomes liquid.
