Explain the conversion of acetic acid into methane and ethane in separate steps. 

Explanation

To convert acetic acid (CH₃COOH) into methane (CH₄) and ethane (C₂H₆), we can follow two separate pathways. Here’s a step-by-step explanation for each conversion:

### Conversion of Acetic Acid to Methane

1. **Formation of Sodium Acetate**:
- First, acetic acid reacts with sodium hydroxide (NaOH) to form sodium acetate (CH₃COONa).
- Reaction:
\[
