Answer 2

The silver halides are used in photography because of the light-sensitive nature of the silver.

Explanation:

The silver halides including AgCl, AgBr and AgI is used in photography.

AgCl when heated, silver along with chloride are obtained. The balanced reaction is $2AgCl \xrightarrow{sunlight/heat} 2Ag + Cl_2$. So, M = AgCl and N= $Cl_2$.

This reaction is in black and white photography. So, O= Black and white photography.

It is an example of thermal decomposition. This because we are using heat that causes breaking or decomposition of the AgCl. So, P= Thermal decomposition.
