Question

Draw orbit structure diagram of Calcium oxide \[\left( {CaO} \right)\].

Answer 1

Hint:In the given question firstly we have to define the facts regarding the polarity and the no polarity and the basic definition. Calcium oxide (CaO), its other names are quicklime or burnt lime. It is a widely used chemical compound in industrial areas. It is white in colour, , alkaline in nature and crystalline solid at room temperature.

Complete step-by-step answer:The given question statement asks about the structure of the compound of calcium oxide, the integrative structure of the elements as a self and in the compound as a molecule.

Calcium oxide (CaO), is also known as quicklime or burnt lime. It is a widely used chemical compound. It is a white in colour , alkaline in nature, crystalline solid at room temperature. The broadly used term "lime" denotes calcium-containing inorganic materials, in which carbonates, oxides and hydroxides of calcium, silicon, magnesium, aluminium, and iron predominate. The name quicklime specifically used for only one chemical compound calcium oxide. Calcium oxide that survives processing without reacting in building products such as cement is called free lime.] Calcium oxide is made up by heating limestone ( $CaC{O_3}$ ). On heating $C{O_2}$ gas evolves and $CaO$ is formed
$CaC{O_3} \to CaO + C{O_2}$
Quicklime is relatively inexpensive. $CaO$ and its chemical derivative (calcium hydroxide, of which quicklime is the anhydride) are important commodity chemicals.

Note:Quicklime and hydrated lime is used to increase the load carrying capacity of clay-containing soils. They do this by reacting finely with divided silica and alumina to produce calcium silicates and aluminates, which possess cementing properties.
