Two examples of decomposition reactions in every day life are the decomposition of hydrogen peroxide, and the decomposition of carbonic acid.

#### Explanation:

Two examples of decomposition reactions in every day life are:

Decomposition of Hydrogen Peroxide

$\text{H"_2"O"_2}$$\rightarrow$$\text{H"_2"O" + "O"_2}$

Decomposition of hydrogen peroxide occurs spontaneously, and slowly over time, but is more rapid when exposed to light. That is why hydrogen peroxide bottles are dark and plastic so they block out the light, and so no trace metallic impurities that may be present in glass will not be a problem.
$\text{H"_2"CO"_3}$$\rightarrow$$\text{H"_2"O"+"CO"_2}$
