An aqueous solution of sodium carbonate absorbs `NO` and `NO_(2)` to yield

Options

A. `CO_(2) + NaNO^(3)`
B. `CO_(2) + NaNO_(2)`
C. `NaNO_(2) + CO`
D. `NaNO_(3) + CO`

Explanation

To solve the problem of what products are formed when an aqueous solution of sodium carbonate absorbs NO and NO2, we can break down the process into a series of steps:

### Step 1: Identify the initial reaction
When sodium carbonate (Na2CO3) is in an aqueous solution, it can react with nitrogen oxides (NO and NO2). The first step is to consider how NO and NO2 interact in the presence of water.

**Hint:** Think about the reactions of nitrogen oxides with water and how they may form acids.

### Step 2: Reaction of NO and NO2
NO can react with NO2 in the presence of water to form nitrous acid (HNO2). The reaction can be represented as:
\[ NO + NO2 + H2O \rightarrow HNO2 \]

**Hint:** Remember that nitrogen oxides can form acids when they react with water.

### Step 3: Reaction of HNO2 with Sodium Carbonate
Next, the nitrous acid (HNO2) formed will react with sodium carbonate (Na2CO3). The reaction can be represented as:
\[ HNO2 + Na2CO3 \rightarrow NaNO2 + H2CO3 \]

**Hint:** Consider how acids react with carbonates to produce salts and carbonic acid.

### Step 4: Decomposition of Carbonic Acid
Carbonic acid (H2CO3) is unstable and will decompose into water (H2O) and carbon dioxide (CO2):
\[ H2CO3 \rightarrow H2O + CO2 \]

**Hint:** Remember that carbonic acid is a weak acid and tends to decompose easily.

### Step 5: Final Products
Combining all the reactions, the final products of the reaction when an aqueous solution of sodium carbonate absorbs NO and NO2 are:
- Sodium nitrite (NaNO2)
- Carbon dioxide (CO2)

Thus, the overall reaction can be summarized as:
\[ Na2CO3 + NO + NO2 + H2O \rightarrow NaNO2 + CO2 + H2O \]

### Conclusion
The products formed when an aqueous solution of sodium carbonate absorbs NO and NO2 are sodium nitrite (NaNO2) and carbon dioxide (CO2).

**Final Answer:** Sodium nitrite (NaNO2) and carbon dioxide (CO2).
