• Carbonate chemistry — Science Learning Hub

    Calcium oxide is known as lime and is one of the top 10 chemicals produced annually by thermal decomposition of limestone. The thermal decomposition of calcium carbonate to lime is one of the oldest chemical reactions known. For several thousand years, lime has been used in mortar (a paste of lime, sand and water) to cement stones to one ...

  • How Does Limestone Affect the Environment? | Reference

    While limestone itself doesn't affect the environment, limestone mining can have a negative impact. On the other hand, the environment can affect limestone by breaking it down. Limestone mining can pollute water and create sinkholes. When limestone dissolves while it's still in the ground, caves and gullies form, a natural phenomenon known as ...

  • Thermal decomposition of calcium carbonate- Learn Chemistry

    Calcium carbonate is strongly heated until it undergoes thermal decomposition to form calcium oxide and carbon dioxide. The calcium oxide (unslaked lime) is dissolved in water to form calcium hydroxide (limewater). Bubbling carbon dioxide through this forms a milky suspension of calcium carbonate.

  • What is the thermal decomposition of limestone? | AnswersDrive

    Thermal decomposition, or thermolysis, is a chemical decomposition caused by heat. The decomposition temperature of a substance is the temperature at which the substance chemically decomposes. The reaction is usually endothermic as heat is required to break chemical bonds in the compound undergoing decomposition.

    In limestone calcination, a decomposition process, the chemical reaction is CaCO 3 → CaO + CO 2 (g). The standard Gibbs free energy of reaction is approximated as ΔG° r = 177,100 − 158 T (J/mol). The standard free energy of reaction is 0 in this case when the temperature, T, is equal to 1121 K, or 848 °C. Oxidation. In some cases, calcination of a metal results in oxidation of the metal.
