To match the structural formula to the chemical formula, let's analyze each of the given structural formulas and compare them to the potential chemical formulas provided.

1. Structural Formula: HCOOH

First, let's understand the structural formula "HCOOH":
- HCOOH represents Formic Acid.
- In this formula:
- "H" stands for one hydrogen atom.
- "C" stands for one carbon atom.
- "O" stands for one oxygen atom.
- The second "O" and the final "H" complete the molecule with an additional oxygen atom and hydrogen atom.

Therefore, totaling the atoms in HCOOH, we have:
- 1 Carbon (C)
- 2 Hydrogens (H)
- 2 Oxygens (O)

So, the chemical formula is:
- CH₂O₂

2. Potential Matches:
- [tex]$HCOOH$[/tex] (structural formula)
- [tex]$C _2 H _6 O$[/tex] (chemical formula)
- [tex]$CH _2 O _2$[/tex] (chemical formula)
- [tex]$HOCOOH$[/tex] (structural formula)

To match the structural formula HCOOH to its corresponding chemical formula, we can see:

- HCOOH matches with:
- 1 Carbon (C)
- 2 Hydrogens (H)
- 2 Oxygens (O)

Therefore, the correct match for HCOOH is:
- CH₂O₂

Thus, the structural formula [tex]$HCOOH$[/tex] corresponds to the chemical formula [tex]$CH _2 O _2$[/tex].
