1.	The following diagram displays a chemical reaction. Observe carefully and answer the following questions:(i) Identify the type of chemical reaction that will take place and define it. How will the colour of the salt change ?(ii) Write the chemical equation of the reaction that takes place.(iii) Mention one commercial use of this salt.
Answer» (i) Photochemical decomposition: single reactant breaks down to give simpler products. While silver chloride changes to grey, as it decomposes to silver and chlorine in the presence of sunlight. (ii) 2AgCl(s) +Sunlight → 2Ag(s) + Cl₂(g) (iii) Black and white photography.

Answer»

(i) Photochemical decomposition:

single reactant breaks down to give simpler products.

While silver chloride changes to grey, as it decomposes to silver and chlorine in the presence of sunlight.

(ii) 2AgCl(s) +Sunlight → 2Ag(s) + Cl₂(g)

(iii) Black and white photography.
