Answer 2

The complete question  is as follows :

A metal salt MX when exposed to light splits up to form metal M and a gas X2 . Metal M is used in making ornaments whereas gas X2 is used in making bleaching powder. The salt MX is itself used in black and white photography ? complete the chemical reaction involved .

The metal salt will be silver  chloride .

Silver chloride on exposing to sunlight will decompose into silver and chlorine gas .

This type of reaction is called as Photo chemical reaction where sunlight is used to start the decomposition reaction.

                          sunlight

2AgCl(s)          --------------------> 2Ag (s)  + Cl₂ (g)

silver chloride                        silver        chlorine
