An aqueous solution of metal nitrate (P) reacts with sodium bromide solution to form an yellow precipitate of a compound (Q) which is used in photography. Q on exposure to sunlight, undergoes decomposition reaction to form the metal present in P along with a reddish brown gas Write the chemical reaction and the type of chemical reaction.

An aqueous solution of metal nitrate (P) reacts with sodium bromide so

1.	An aqueous solution of metal nitrate (P) reacts with sodium bromide solution to form an yellow precipitate of a compound (Q) which is used in photography. Q on exposure to sunlight, undergoes decomposition reaction to form the metal present in P along with a reddish brown gas Write the chemical reaction and the type of chemical reaction.
Answer» SOLUTION :`AgNO_3+NaBrtoAgBr+NaNO_3` This is double displacement REACTION. `2AgBr(s)TO2AG(s)+Br_2(G)` This is Photochemical decomposition
