Lime is produced by heating the limestone in a hot kiln write equarion of this chemical reaction

When limestone is heated in a kiln, the calcium carbonate breaks down into calcium oxide and carbon dioxide. This type of reaction is called thermal decomposition. The process is called calcining. Once burnt limestone turns into calcium oxide which is known as quicklime. Limestone is a sedimentary rock mainly made up of calcium carbonate, CaCO3. It

    Although we almost always write the equation for this reaction as one-way, it is in fact reversible. CaCO 3 (s) CaO(s) + CO 2 (g) When you heat limestone in the open air, of course, the carbon dioxide just gets lost and the back reaction can't happen. In an enclosed kiln, though, it can. The net effect of this is to stop the limestone decomposing

    Lime is produced by calcining limestone at 825 C in a lime kiln. The cost of this processing is reflected in the cost of the lime produced which is considerably more than that of limestone. The cost of transporting lime is also higher than that of limestone as lime must be protected from moisture

    This takes place in a furnace called a lime kiln which rotates and the limestone is heated by current of strong hot air. Since this is a reversible reaction, the carbon dioxide produced is carried out of the kiln (so that it doesn’t react back with the calcium oxide to produce calcium carbonate). The calcium oxide is removed at the bottom of
