Answer 1

The reaction represented by the equation \( \text{CaCO}_3 \rightarrow \text{CaO} + \text{CO}_2 \) is a **decomposition reaction**. In this type of reaction, a single compound breaks down into two or more products. In this case, calcium carbonate (CaCO₃) decomposes into calcium oxide (CaO) and carbon dioxide (CO₂).
