On heating lead nitrate forms oxides of nitrogen and lead. The oxides formed are :

Options

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

Explanation

To solve the question regarding the products formed when lead nitrate is heated, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Compound**: The compound in question is lead nitrate, which has the chemical formula \( \text{Pb(NO}_3\text{)}_2 \).

2. **Heating the Compound**: When lead nitrate is heated, it undergoes thermal decomposition. This means it breaks down into simpler substances.

3. **Write the Decomposition Reaction**: The decomposition of lead nitrate can be represented by the following chemical equation:
\[ \text{2 Pb(NO}_3\text{)}_2 \rightarrow 2 \text{PbO} + 4 \text{NO}_2 + \text{O}_2 \]
Here, lead nitrate decomposes to form lead oxide, nitrogen dioxide, and oxygen.

4. **Identify the Products**: From the balanced equation, we can identify the products:
- **Lead Oxide**: \( \text{PbO} \)
- **Nitrogen Dioxide**: \( \text{NO}_2 \)
- **Oxygen**: \( \text{O}_2 \)

5. **Conclude the Oxides Formed**: The question specifically asks for the oxides formed. The oxides formed upon heating lead nitrate are:
- **Oxide of Lead**: \( \text{PbO} \)
- **Oxide of Nitrogen**: \( \text{NO}_2 \)

### Final Answer:
The oxides formed when lead nitrate is heated are:
- Lead Oxide (\( \text{PbO} \))
- Nitrogen Dioxide (\( \text{NO}_2 \))
