Question

Which form of energy is absorbed during the decomposition of silver bromide?

• A. Electrical energy
• B. Light energy
• C. Heat energy
• D. Chemical energy

Answer 1

Answer:

B. Light energy

Silver bromide (AgBr) is a light-sensitive compound that decomposes when exposed to light.

Decomposition Reaction:

The decomposition reaction of silver bromide is:

2AgBr → 2Ag + Br₂

Energy Absorbed:

During this reaction, light energy is absorbed, which provides the necessary energy for the decomposition to occur.

Type of Energy:

The energy absorbed is in the form of photons, which are packets of electromagnetic radiation, including visible light.
