Answer 2

Answer:

Explanation:

Define:- Decomposition reaction:- The reaction in which a single compound splits into two or more simple substances under suitable conditions.  

This reaction is opposite to combination reaction.

General formula:- AB -----> A + B

--> On the basis of the form of energy required for the reaction, these reactions are three types:-

 (i) Thermal decomposition

 (ii) Electrolysis decomposition

(iii) photochemical decomposition

Examples:-

(i)     CaCO3(s)  ----->  CaO(s)   +  CO2 (g)    (Thermal)

   Lime stone          Calcium   Carbon  

             Oxide   dioxide

(ii)     2NaCl(l)  ----->   2Na(s)   +  Cl2 (g)      (Electrolysis)

   Sodium Chloride  Sodium  Chlorine

(iii)   2AgCl(l)         ----->   2Ag(s)          +  Cl2 (g)     (photochemical)

  Silver Chloride            Silver              Chlorine
