Final answer:
The hypothetical chemical formula for combining CO₂ with one fluorine atom would be CO₂F, but this does not correspond to a known stable molecule.
Step-by-step explanation:
The chemical formula for the compound formed from the addition of one fluorine atom (F) to carbon dioxide (CO₂) can be deduced from the rules of writing formulas for covalent compounds. The subscripts in a chemical formula represent the number of each type of atom present in the compound. Therefore, when we combine CO₂ (carbon dioxide) with one atom of fluorine, we obtain the formula CO₂F. However, this particular compound seems hypothetical and does not correspond to any known stable molecule. Typically, carbon dioxide does not combine directly with fluorine to form a stable compound. The closest known compound is carbonyl fluoride, with the formula COF₂, where carbon forms a double bond with each oxygen and a single bond with each fluorine atom.
