### Step-by-Step Solution: **1. Resonance Structures of CH₃COO⁻ (Acetate Ion)** - **Structure 1**: The first resonance structure of acetate ion is as follows: - The carbon atom (C) is bonded to three hydrogen atoms (H) and one oxygen atom (O) with a single bond. This oxygen atom carries a negative charge (O⁻). - The carbon atom is also double-bonded to another oxygen atom (O) which is neutral. ...
