Explanation:

A chemical formula uses symbols to show elements and sub - scripts for atom counts. "carbon oxide" is a name, not a formula. "iron" is an element symbol (Fe), but just saying "iron" isn't a formula representation. NaCl shows 1 Na and 1 Cl atom. CO₂ shows 1 C and 2 O atoms. C₆H₁₂O₆ shows 6 C, 12 H, and 6 O atoms.

Answer:

NaCl, CO₂, C₆H₁₂O₆
