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.

The Cycle of Reactions involving Limestone and Products Made From it. Limestone is a sedimentary rock composed mainly of calcium carbonate (CaCO3). When limestone is heated, it undergoes a chemical reaction called thermal decomposition. This process turns calcium carbonate into calcium oxide and carbon dioxide (CaCO3 -> CaO + CO2).

Carmeuse Majan, a Salalah Free Zone company, has made solid industrial production ground in Salalah. In three years the company is not only able to operate full capacity of 400 tonnes per day (tpd) with one kiln; it is ready for growth depending upon availability of natural gas, which is crucial for any expansion.
The rock components of the crust are slowly but constantly being changed from one form to another and the processes involved are summarized in the rock cycle (Figure (PageIndex{3})). The rock cycle is driven by two forces: (1) Earth's internal heat engine, which moves material around in the core and the mantle and leads to slow but …
Over millions of years, these deposits are compressed to form limestone, which can be fine or coarse-grained, depending on the origin. The Metamorphic Route. One route that the life cycle of limestone can take is its metamorphosis into marble. It is formed over millions of years when limestone is subjected to intense pressure.

What is the carbon cycle? Carbon is transferred between the ocean, atmosphere, soil, and living things over time scales of hours to centuries.For example, photosynthesizing plants on land remove carbon dioxide directly from the atmosphere, and those carbon atoms become part of the structure of the plants. As plants are eaten by herbivores and …
