Write the resonance structures for `SO_(3)`,`NO_(2)`, and `NO_(3)^(ө)`.

Explanation

To write the resonance structures for \( SO_3 \), \( NO_2 \), and \( NO_3^- \), we need to follow a systematic approach. Let's break down the process step by step.

### Step 1: Draw the Lewis Structure for \( SO_3 \)

1. **Count the valence electrons**: Sulfur (S) has 6 valence electrons and each oxygen (O) has 6, so for \( SO_3 \):
\[ 6 + (3 \times 6) = 24 \text{ valence electrons} \]
