Calcium carbonate breaks down into calcium oxide and liberates carbon dioxide. The whole reaction is driven by heat. What type of reaction is this?

Thermal decomposition

Explanation:

Decomposition is a type of chemical reaction in which one reactant forms two or more than two products.

Decomposition reactions require breaking of bonds which require energy and thus all of the decomposition reactions are endothermic reactions. They require energy in the form of heat, electricity or sunlight and thus called as thermal, electrolytic and photolytic decomposition respectively.

The decomposition reaction for calcium carbonate breaks down into calcium oxide and liberates carbon dioxide is :

hope this

explanation:

covalent bonds

consist of pairs of electrons shared by two atoms, and bind the atoms to fixed orientation and requre high energies to break them

ionic bonds

when two atoms differ considerably in their electronegativity, then one of the atoms will lose its electron to the other atom. this results in a positively charged ion(cation) and a negatively charged ion (anion)
