Respuesta :
Calcium oxide (CaO) or lime in solid form can be prepared from the decomposition of calcium hydroxide {Ca[tex](OH)_{2}[/tex] in to lime (CaO) and water ([tex]H_{2}O[/tex] at high temperature. The reaction is an endothermic reaction. That is heat is absorbed in this reaction process. One mole of calcium hydroxide decomposed into one mole of calcium oxide and one mole of water. The balanced reaction can be shown as-CaC[tex]O_{3}[/tex] (solid) → CaO (solid) + [tex]H_{2}O[/tex] (liquid). The heat of the reaction is (+) 63.7 kJ/mole of CaO.
A balanced chemical equation is the equal number of atoms of the same element on both sides of the reaction. The balanced chemical reaction is, [tex]\rm Ca(OH)_{2}(s) \rightarrow CaO(s) + H_{2}O(g)[/tex].
What is decomposition reaction?
Decomposition is a chemical reaction in which a single reactant decomposes or breaks to produce two or more products.
Solid calcium hydroxide [tex](\rm Ca(OH)_{2})[/tex] decomposes to form solid calcium (ii) oxide (lime) [tex](\rm CaO)[/tex] and water vapour [tex](\rm H_{2}O)[/tex]
The decomposition of the reactant is an endothermic reaction and its 1 mole produces 1 mole of each reactant. The balanced chemical reaction can be given as,
[tex]\rm Ca(OH)_{2}(s) \rightarrow CaO(s) + H_{2}O(g)[/tex]
Therefore, the balanced chemical reactions have the same and equal atoms on both sides.
