Natural gas is a mixture of

Options

A. `CO+CO_(2)`
B. `CO+N_(2)`
C. `CO+H_(2)+CH_(4)`
D. `CH_(4)+C_(2)H_(6)+C_(3)H_(8)`

Answer

**Step-by-Step Solution:**

1. **Definition of Natural Gas**: Natural gas is defined as a fossil fuel that occurs naturally in the environment. It is primarily composed of various gases.

2. **Main Component**: The primary component of natural gas is methane (CH₄), which constitutes about 70-90% of the mixture.

3. **Other Components**: In addition to methane, natural gas also contains other hydrocarbons, including:
- Ethane (C₂H₆)
- Propane (C₃H₈)
- Butane (C₄H₁₀)

4. **Composition Summary**: Therefore, natural gas is a mixture of:
- 70-90% Methane
- Ethane
- Propane
- Butane

5. **Conclusion**: Thus, the correct answer to the question is that natural gas is a mixture of methane, ethane, propane, and butane.
