<span>An example of spontaneous decomposition is that of hydrogen peroxide, which will slowly decompose into water and oxygen:
2 H2O2 → 2 H2O + O2
Carbonates will decompose when heated, a notable exception being that of carbonic acid, H2CO3. Carbonic acid, the "fizz" in sodas, pop cans and other carbonated beverages, will decompose over time (spontaneously) into carbon dioxide and water
H2CO3 → H2O + CO2
Other carbonates will decompose when heated producing the corresponding metal oxide and carbon dioxide. In the following equation M represents a metal:
MCO3 → MO + CO2
A specific example of this involving calcium carbonate:
CaCO3 → CaO + CO2
Metal chlorates also decompose when heated. A metal chloride and oxygen gas are the products.
2 MClO3 → 2 MCl + 3 O2
A common decomposition of a chlorate to evolve oxygen utilizes potassium chlorate as follows:
2 KClO3 → 2 KCl + 3 O2</span>

Explanation:
Since everything is made of atoms there has to be something to keep all of them together that's where the nucleus comes in it's the one atom that differs from the other even though there are many different atoms the nucleus is special in that it's made up of neutrons and protons and maybe some electrons.
