Detailed Solution

The given statement is true.
Concept- Usually decomposition reactions are responsible for black and white photography.
The balanced equation is that equation in which the number of molecules on the reactants side is equal to that on the products side. Therefore, the balanced chemical reaction for black and white photography are as follows:
2AgCl (s) 🡪 2Ag + Cl2
The other reaction involved is bromine.
2AgBr (s) 🡪 2Ag + Br2
So, the correct answer is 2AgCl (s) 🡪 2Ag + Cl2.
Hence, the given statement is true.
