Example : melting of ice
[tex]H_2O(s)\rightarrow H_2O(l)[/tex]
A chemical reaction is defined as the reaction in which a change in chemical composition takes place. A new substance is formed in these reactions by breaking of old and making of new bonds.
Example: Oxidation of magnesium leads to formation of white magnesium oxide and is a chemical change.
[tex]2Mg+O_2\rightarrow 2MgO[/tex]
