When ethane is heated with air at `500^(@)`C, we get

Options

A. ethylene and hydrogen
B. acetaldehyde
C. carbon dioxide and water
D. None of these

Explanation

To solve the question of what products are formed when ethane (C2H6) is heated with air at 500°C, we can follow these steps:

### Step 1: Write the chemical equation for the combustion of ethane.
When ethane combusts in the presence of oxygen, it can be represented by the following balanced chemical equation:

\[ 2 \text{C}_2\text{H}_6 + 7 \text{O}_2 \rightarrow 4 \text{CO}_2 + 6 \text{H}_2\text{O} \]

### Step 2: Identify the reactants and products.
In this reaction:
- **Reactants**: Ethane (C2H6) and Oxygen (O2)
- **Products**: Carbon Dioxide (CO2) and Water (H2O)

### Step 3: Analyze the conditions of the reaction.
The reaction is carried out at a high temperature of 500°C, which is sufficient to promote the combustion of ethane in the presence of oxygen.

### Step 4: Conclude the products formed.
From the balanced equation, we can see that when ethane is heated with air (which contains oxygen), the products formed are:
- 4 moles of Carbon Dioxide (CO2)
- 6 moles of Water (H2O)

### Final Answer:
Therefore, when ethane is heated with air at 500°C, the products formed are carbon dioxide and water.
