Question

When a compound x is placed under sunlight it turns grey give the name of reaction and write the balanced chemical equation?

Answer 1

Answer:

• The name of reaction is Photochemical decomposition.
• The substance can be Silver chloride (AgCl)  or also Silver bromide (AgBr).

Explanation:

• A decomposition reaction is the type of reaction by which a substance breaks down into two or more simpler substances.
• Whatever energy is provided in the form of heat, electricity, or light energy will aid in the bond breaking of complex chemicals to produce simpler substances in a decomposition chemical reaction.
• Bond breaking consumes energy, hence decomposition reactions are always endothermic processes.
• When a decomposition reaction takes place in the presence of light, it is referred to as photochemical decomposition.
• Silver chloride and silver bromide undergo photochemical decomposition to produce silver and chlorine or bromine gas, respectively.

          2AgCl ⇒ 2Ag + Cl₂

         2AgBr ⇒ 2Ag + Br₂

Answer 2

The name of reaction is Photochemical decomposition.

The chemical substance can be Silver chloride (AgCl)  or also Silver bromide (AgBr).

Explanation:

• Decomposition reaction is the reaction in which the substance breaks down into two or more simpler substances.

• Energy is provided in the form of heat, electricity, or light energy .
• They will aid in the breaking of bond of complex chemicals into  simpler substances in a decomposition chemical reaction.

• The  breaking of bond will consume energy, hence decomposition reactions are always endothermic processes.

• When a decomposition reaction takes place in the presence of light, it is referred to as photochemical decomposition.

• Silver chloride and silver bromide undergo photochemical decomposition to produce silver and chlorine or bromine gas, respectively.
