Draw the Lewis structures for the following molecules and ion:
HCOOH

Explanation

To draw the Lewis structure for HCOOH (formic acid), follow these steps:

### Step 1: Count the total number of valence electrons.
- Carbon (C) has 4 valence electrons.
- Each Oxygen (O) has 6 valence electrons, and there are 2 Oxygens: 2 × 6 = 12.
- Each Hydrogen (H) has 1 valence electron, and there are 2 Hydrogens: 2 × 1 = 2.

**Total valence electrons = 4 (C) + 12 (O) + 2 (H) = 18 valence electrons.**
