Define the term decomposition reaction . Give one example each of thermal decomposition and electrolytic decomposition.

Explanation

In a decomposition, a single reactant breaks down into two or more simple products .
When a decomposition reaction is carried out by heating , it is called thermal decomposition reaction .
`underset(("Calcium carbonate"))(CaCO_(3)(s))overset ("Heat") rarr underset(("Calcium oxide"))(CaO(S))+underset(("Carbon dioxide"))(CO_(2)(g))`
When a decomposition reaction is carried out with the help of electric current, the process is called electrolysis .
`underset("Water")(2H_(2)O(1))overset("Electric current") rarr underset(("Hydrogen gas"))(2H_(2)(g))+underset(("Oxygen gas"))(O_(2)(g))`
