Dissociation reaction of ferric hydroxide to ferric oxide and water. The molecular equation of the reaction can be written as follows:

Fe (OH) 3 = Fe2O3 + 3 H2O

The reaction takes place between substances such as phosphorus and oxygen. As a result of the reaction, a substance is formed: pentavalent phosphorus oxide. The molecular equation of the reaction can be written as follows:

4 P + 5 O2 = 2 P2O5

Dissociation reaction of calcium carbonate to calcium oxide and carbon dioxide. The molecular equation of the reaction can be written as follows:

CaCO3 = CaO + CO2

Lithium oxide react with water. As a result of this reaction, lithium hydroxide is formed and hydrogen gas is released. The molecular equation of the reaction can be written as follows:

Li2O + H2O = LiOH + H2.
