An aqueous solution of Silver nitrate reacts with sodium bromide solution to form yellow ppt of compound
Silver bromide which is used in photography.
IT IS A DOUBLE DISPLACEMENT reaction where mutual exchange of ions takes between reactants.
BALANCED CHEMICAL EQUATION:
2Ag (NO3) (aq)+ 2 NaBr (aq) -----> 2AgBr (s) + NaNO3 (aq)
Element P = Silver Nitrate
Element Q = Silver Bromide which is used in photography.

Silver Bromide on exposed to sunlight decomposes to silver metal and brown Bromine gas.
It is Photo chemical decomposition reaction where compound split up into it's constituents by sunlight energy.
BALANCED CHEMICAL Equation:
2AgBr-----> 2Ag (s) + Br2 ( g).
