On heating a mixture of sodium propanoate and sodalime ____is formed (propane/ethane)

Explanation

To solve the question of what is formed when a mixture of sodium propanoate and soda lime is heated, we can follow these steps:

### Step 1: Understand the Reactants
- Sodium propanoate is the sodium salt of propanoic acid, which has the formula CH3CH2COONa.
- Soda lime is a mixture of sodium hydroxide (NaOH) and calcium oxide (CaO).

### Step 2: Identify the Reaction
- When sodium propanoate is heated with soda lime, a decarboxylation reaction occurs. Decarboxylation involves the removal of a carboxyl group (-COOH) from a compound, releasing carbon dioxide (CO2).
