Question

an aqueous solution of metal nitrate P reacts with sodium bromide solution to form yellow ppt of compound Q which is used in photography. Q on exposure to sunlight undergoes decomposition reaction to form metal present in P along with reddish brown gas. Identify P and Q .write the chemical reaction and type of reaction​

Answer 1

Answer:

p = chloride ,q = silver ,

AgCl --------> Ag2 + Cl2

this is decomposition reaction .

Answer 2

Answer:

P = AgNO3 , Q = AgBr

2AgBr (s) 2Ag (s) + Br2 (g)

Photochemical decompositio
