Write chemical equation of decarboxylation of ethanoic acid.

Explanation

To write the chemical equation for the decarboxylation of ethanoic acid, we need to follow these steps:

### Step-by-Step Solution:

1. **Identify the Reactants**: The primary reactant in this reaction is ethanoic acid (also known as acetic acid), which has the chemical formula CH₃COOH. The reagent used for decarboxylation is soda lime, which is a mixture of calcium oxide (CaO) and sodium hydroxide (NaOH).

2. **Understand Decarboxylation**: Decarboxylation is the process of removing a carboxyl group (-COOH) from a carboxylic acid, resulting in the release of carbon dioxide (CO₂). In the case of ethanoic acid, the carboxyl group will be removed, leading to the formation of methane (CH₄).
