उत्तर
When 2 g of silver chloride, AgCl, is kept in sunlight then AgCl breaks down into Ag and C12. The color of the silver chloride turns to grey.
The following change can be represented by the chemical reactions as:
\[\ce{2AgCl(s)->[sunlight] 2Ag(s) + Cl2(g)}\].
This type of reaction is an example of a photochemical decomposition reaction.
