Question

Solid calcium carbonate(CaCO3) is formed by the reaction of solid calcium oxide and carbon dioxide gas .
Write a balanced chemical equation for this reaction.

Answer 1

Answer:

caco3 (s)---heat---cao(s) + co2 (g)

Explanation:

calcium oxide is called lime or quick lime. it

has many uses one is in manufacture of cement

when decomposition reaction is carried out by heating, it is called thermal decomposition

Answer 2

Answer:

The reaction of formation of calcium carbonate from calcium oxide and carbon dioxide gas is given below:

$\[CaO\left( s \right) + C{O_2}\left( g \right) \to CaC{O_3}\left( s \right)\]$

Explanation:

This reaction is an example of a combination reaction. In a combination reaction, two or more two reactants combine to give a single product.

In the given reaction two reactants carbon dioxide and calcium oxide combined to give calcium carbonate.

$\[CaO\left( s \right) + C{O_2}\left( g \right) \to CaC{O_3}\left( s \right)\]$
