Which of the following is an example of a decomposition reaction?
Understand the Problem
The question is asking for an example of a decomposition reaction from a given set of chemical equations.
Answer
CaCO3 → CaO + CO2
The final answer is CaCO3 → CaO + CO2.
Answer for screen readers
The final answer is CaCO3 → CaO + CO2.
More Information
A decomposition reaction involves the breakdown of a single compound into two or more products. In this case, calcium carbonate (CaCO3) decomposes into calcium oxide (CaO) and carbon dioxide (CO2).
Tips
Common mistake is confusing decomposition with synthesis or combustion reactions. Always look for reactions with one reactant producing multiple products.
