Nature of the products obtained by complete combustion of methane is

Options

A. acidic, basic
B. acidic, neutral
C. basic, neutral
D. both are neutral

Answer

To determine the nature of the products obtained by the complete combustion of methane, we can follow these steps:

### Step 1: Write the chemical equation for the combustion of methane.
The complete combustion of methane (CH₄) in the presence of oxygen (O₂) produces carbon dioxide (CO₂) and water (H₂O). The balanced chemical equation is:

\[ \text{CH}_4 + 2\text{O}_2 \rightarrow \text{CO}_2 + 2\text{H}_2\text{O} \]

### Step 2: Identify the products of the reaction.
From the balanced equation, the products of the combustion of methane are:
- Carbon dioxide (CO₂)
- Water (H₂O)

### Step 3: Determine the nature of each product.
- **Carbon dioxide (CO₂)**: This is a non-metal oxide. Non-metal oxides are generally acidic in nature. Therefore, CO₂ is considered acidic.
- **Water (H₂O)**: Water is a neutral substance. It does not exhibit acidic or basic properties under normal conditions.

### Step 4: Conclude the overall nature of the products.
Since one product (CO₂) is acidic and the other product (H₂O) is neutral, we can conclude that the nature of the products obtained from the complete combustion of methane is:
- **Acidic and Neutral**.

### Final Answer:
The nature of the products obtained by the complete combustion of methane is **acidic and neutral**.
