Sodium Bromide is added to an aqueous solution of a metal nitrate A. A yellow precipitate B is obtained which is used in photography. Compound B is photosensitive and decomposes to its constituents on exposure to sunlight, accompanied by the evolution of a reddish- brow gas. Write down the balanced equation and identify A, B and C.

Hey Annannuu.....
Have a look for your answer friend-------->
A. Silver (metal)
B. Silver Bromide (AgBr) which is used in photography.
And Reaction is ---------->
☆ NaBr + AgNO3 ----------> AgBr (yellow ppt.) + NaNO3 (aq)☆
[ it is a double displacement reaction]
When compound B is exposed in sunlight then it decomposes into it's constitutes such as-------
2AgBr (sunlight)------------> 2Ag(s) + Br2(g)
☆ C. Bromine gas (Br2) which is reddish brown in colour.
HOPE IT WILL HELP YOU!!!
THANKS!!!
