How many type of products are obtained on thermal decomposition of alkaline earth metal nitrates.

Answer

To determine how many types of products are obtained from the thermal decomposition of alkaline earth metal nitrates, we can follow these steps:

### Step 1: Write the General Reaction
The general reaction for the thermal decomposition of alkaline earth metal nitrates can be represented as:
\[ \text{M(NO}_3\text{)}_2 \rightarrow \text{MO} + \text{2NO}_2 + \text{1/2O}_2 \]
where M represents any alkaline earth metal (such as Beryllium, Magnesium, Calcium, etc.).

### Step 2: Identify the Products
From the reaction, we can identify the products formed:
1. **Metal Oxide (MO)** - This is a solid product.
2. **Nitrogen Dioxide (NO2)** - This is a gas product.
3. **Oxygen (O2)** - This is also a gas product.

### Step 3: Count the Types of Products
Now, we can categorize the products:
- **1 Solid Product**: Metal Oxide (MO)
- **2 Gas Products**: Nitrogen Dioxide (NO2) and Oxygen (O2)

### Step 4: Conclusion
In total, we have:
- 1 type of solid product
- 2 types of gas products

Thus, the total number of different types of products formed is **3**.

### Final Answer
The thermal decomposition of alkaline earth metal nitrates yields **3 types of products**: Metal Oxide (solid), Nitrogen Dioxide (gas), and Oxygen (gas).
