In the above double displacement reaction, exchange of ions take place and aqueous solution of sodium chloride and white coloured precipitate of barium sulphate are formed . If the reactants are taken in solid state i.e. other than aqueous state then the reaction won't take place cause a precipitate is formed only when we mix two aqueous solutions ( also exchange of ions won't take place).

Chemical reaction is a process in which two substances react together and in that , a rearrangement of atomic bonds takes place . Chemical equation is just simple, it means writing the reaction using symbols of the elements and compounds involved in it
