Options

A. `N_(2)O,NO`
B. `N_(2)O,NO_(2)`
C. `NO,NO_(2)`
D. `NO_(2),N_(2)O`

Explanation

To solve the question regarding the gases produced in the reactions of \( Pb(NO_3)_2 \) and \( NH_4NO_3 \) upon heating, we will analyze each reaction step by step.

### Step 1: Analyze the decomposition of \( Pb(NO_3)_2 \)

1. **Write the reaction**: When lead(II) nitrate, \( Pb(NO_3)_2 \), is heated, it decomposes.
\[ Pb(NO_3)_2 \xrightarrow{\Delta} PbO + 2NO_2 + O_2 \]

2. **Identify the gases produced**: From the reaction, we can see that the gases produced are:
- Nitrogen Dioxide (\( NO_2 \))
- Oxygen (\( O_2 \))

### Step 2: Analyze the decomposition of \( NH_4NO_3 \)

1. **Write the reaction**: When ammonium nitrate, \( NH_4NO_3 \), is heated, it also decomposes.
\[ NH_4NO_3 \xrightarrow{\Delta} N_2O + 2H_2O \]

2. **Identify the gases produced**: From this reaction, the gas produced is:
- Nitrous Oxide (\( N_2O \))

### Step 3: Combine the results

From both reactions, we have:
- From \( Pb(NO_3)_2 \): \( NO_2 \) and \( O_2 \)
- From \( NH_4NO_3 \): \( N_2O \)

### Final Answer

The gases produced in the reactions are:
- **From \( Pb(NO_3)_2 \)**: Nitrogen Dioxide (\( NO_2 \)) and Oxygen (\( O_2 \))
- **From \( NH_4NO_3 \)**: Nitrous Oxide (\( N_2O \))

Thus, the final gases produced in the reactions are:
- **Nitrogen Dioxide (\( NO_2 \)) and Nitrous Oxide (\( N_2O \))**.
