Draw the Lewis structures for the following molecules and ions:
`H_(2)S`,`SiCl_(4)`,`BeF_(2)`,`CO_(3)^(2-)`,`HCOOH`

Explanation

To draw the Lewis structures for the given molecules and ions, we will follow a systematic approach. Here’s a step-by-step solution for each of the compounds:

### 1. Lewis Structure for H₂S (Hydrogen Sulfide)

**Step 1:** Count the valence electrons.
- Sulfur (S) has 6 valence electrons.
- Each Hydrogen (H) has 1 valence electron. For 2 H, that’s 2 electrons.
- Total = 6 (S) + 2 (H) = 8 valence electrons.
