`Na_(2)O + CO_(2) to `…………..

Answer

To complete the reaction between sodium oxide (Na₂O) and carbon dioxide (CO₂), we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Reactants:**
- The reactants in this reaction are sodium oxide (Na₂O) and carbon dioxide (CO₂).

2. **Understand the Reaction Type:**
- This is a combination reaction where two substances combine to form a single product.

3. **Write the Chemical Equation:**
- The reaction can be represented as:
\[ \text{Na}_2\text{O} + \text{CO}_2 \rightarrow ? \]

4. **Determine the Product:**
- When sodium oxide reacts with carbon dioxide, it forms sodium carbonate (Na₂CO₃).

5. **Complete the Chemical Equation:**
- Thus, the complete reaction is:
\[ \text{Na}_2\text{O} + \text{CO}_2 \rightarrow \text{Na}_2\text{CO}_3 \]

6. **Identify the Product:**
- The product, sodium carbonate (Na₂CO₃), is an inorganic compound that is white, odorless, and soluble in water.

### Final Answer:
\[ \text{Na}_2\text{O} + \text{CO}_2 \rightarrow \text{Na}_2\text{CO}_3 \]
