### Selecting the Redox Reaction

**Question 09**: Select the redox reaction from the following list:

**A.** \[\text{CO}_2(\text{s}) \rightarrow \text{CO}_2(\text{g})\]

**B.** \[\text{NH}_3 + \text{HCl} \rightarrow \text{NH}_4\text{Cl}\]

**C.** \[2\text{H}_2\text{O} + \text{O}_2 \rightarrow 2\text{H}_2\text{O}_2\]

**D.** \[2\text{HNO}_3 + \text{Ca(OH)}_2 \rightarrow \text{Ca(NO}_3)_2 + 2\text{H}_2\text{O}\]

**E.** \[\text{CaCl}_2 + \text{Na}_2\text{CO}_3 \rightarrow \text{CaCO}_3 + 2\text{NaCl}\]

**Note**: Please explain which reaction is a redox reaction.

### Explanation:

A **redox reaction** involves the transfer of electrons between two species. This can be identified by changes in oxidation states of elements between reactants and products. Analyze each option to determine if it fits the criteria of a redox reaction.
