What is a decomposition reaction?

• A. A reaction where two compounds exchange ions
• B. A reaction in which a single compound breaks down
• C. A reaction where two substances combine into one
• D. A reaction that involves oxidation

Answer: (B)

A decomposition reaction is characterized by a process in which a single compound undergoes a transformation to break down into two or more simpler substances or components. This type of reaction can occur due to various factors, such as heat, light, or the presence of a catalyst. Examples of decomposition reactions include the breakdown of hydrogen peroxide into water and oxygen or the thermal decomposition of calcium carbonate into calcium oxide and carbon dioxide. This understanding of decomposition reactions is fundamental in chemistry, as it highlights how complex substances can transform into simpler entities, which is a key concept in chemical behavior and transformations.
