What is the definition of thermal decomposition?

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.
A.

What is the thermal decomposition of limestone?

Calcium carbonate is strongly heated until it undergoes thermal decomposition to form calcium oxide and carbon dioxide. The c alcium oxide (unslaked lime) is dissolved in water to form calcium hydroxide (limewater) .

  • What is thermal decomposition with example?

    Photo decomposition is a chemical reaction in which a substance is broken down into simple substances by exposure to light (photons). Decomposition of calcium carbonate:Calcium carbonate (lime stone) decomposes into calcium oxide (quick lime) and carbon dioxide when heated.
  • What is lime water in chemistry?

    Limewater. Limewater is the common name for a diluted solution of calcium hydroxide. Calcium hydroxide, Ca(OH)2, is sparsely soluble in water (1.5 g/L at 25 °C). Pure limewater is clear and colorless, with a slight earthy smell and an alkaline bitter taste of calcium hydroxide.
