The addition of `Na_(2)CO_(3)`, to the aqueous solution of an oxide produces `CO_(2)`. This reaction indicates that

Options

A. the oxide is basic
B. the oxide is amphoteric
C. the oxide is that of a metal
D. the oxide is that of a non-metal

Answer

To solve the question regarding the addition of Na₂CO₃ to an aqueous solution of an oxide that produces CO₂, we can follow these steps:

### Step 1: Understand the Reaction
When Na₂CO₃ (sodium carbonate) is added to an aqueous solution of an oxide, it indicates a chemical reaction is taking place. The production of CO₂ gas suggests that the oxide in question is likely reacting with the carbonate.

### Step 2: Identify the Nature of the Oxide
The formation of CO₂ upon the addition of Na₂CO₃ suggests that the oxide is acidic in nature. This is because Na₂CO₃ can react with acids to produce CO₂ gas.

### Step 3: Determine the Type of Oxide
Since the oxide is producing CO₂, it implies that the oxide is not basic or amphoteric. Instead, it is indicative of a non-metal oxide. Non-metal oxides, such as SO₂ or CO₂, are known to be acidic in nature.

### Step 4: Evaluate the Options
Given the options:
1. The oxide is basic.
2. The oxide is amphoteric.
3. The oxide is that of a metal.
4. The oxide is that of a non-metal.

From our analysis, we can conclude that the correct answer is option 4: "The oxide is that of a non-metal."

### Final Conclusion
The addition of Na₂CO₃ to the aqueous solution of an oxide producing CO₂ indicates that the oxide is that of a non-metal.
