`Ca(OH)_(2) + CO_(2) to`……………. + ……………

Answer

To solve the reaction between calcium hydroxide (Ca(OH)₂) and carbon dioxide (CO₂), we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Reactants**:
- The reactants in this reaction are calcium hydroxide (Ca(OH)₂) and carbon dioxide (CO₂).

2. **Write the Chemical Equation**:
- The initial reaction can be written as:
\[ \text{Ca(OH)}_2 + \text{CO}_2 \rightarrow ? \]

3. **Determine the Products**:
- When calcium hydroxide reacts with carbon dioxide, it produces calcium carbonate (CaCO₃) and water (H₂O).
- Therefore, the products can be written as:
\[ \text{CaCO}_3 + \text{H}_2\text{O} \]

4. **Complete the Reaction**:
- Now we can write the complete balanced chemical equation:
\[ \text{Ca(OH)}_2 + \text{CO}_2 \rightarrow \text{CaCO}_3 + \text{H}_2\text{O} \]

5. **Check for Balancing**:
- Count the number of each type of atom on both sides:
- Calcium (Ca): 1 on both sides
- Carbon (C): 1 on both sides
- Oxygen (O): 4 on the left (2 from Ca(OH)₂ and 2 from CO₂) and 4 on the right (3 from CaCO₃ and 1 from H₂O)
- Hydrogen (H): 2 on both sides
- Since all atoms are balanced, the equation is correct.

### Final Answer:
The complete reaction is:
\[ \text{Ca(OH)}_2 + \text{CO}_2 \rightarrow \text{CaCO}_3 + \text{H}_2\text{O} \]
