Question

\( \text{CaCO}_3 (s) \rightarrow \text{CaO} (s) + \text{CO}_2 (g) \) is what type of reaction?

• A. Decomposition
• B. Combination
• C. Displacement
• D. Double displacement

Hint:

Decomposition reactions involve the breakdown of a single compound into two or more products.

Answer 1

The Correct Option is A

This is a \(\textit{decomposition reaction}\) where one reactant (\( \text{CaCO}_3 \)) breaks down into two products (\( \text{CaO} \) and \( \text{CO}_2 \)).
