Which of the following reactions is an example of a decomposition reaction?
medium Q14 of 15
Step-by-Step Solution
Step 1: Identify the concept
The question tests understanding of decomposition reactions where one compound breaks into simpler substances.Step 2: Apply the concept
2H₂O breaking into H₂ and O₂ (electrolysis of water) is a decomposition reaction. Other options represent combination, displacement, or neutralization reactions.Final Answer:
2H₂O → 2H₂ + O₂ → Option BQuick Check:
Chemical reaction type = decomposition ✅
Quick Trick: Decomposition reactions have one reactant and multiple products.
Common Mistakes:
- Confusing decomposition with displacement or combination reactions.
