Answer:

F

Step-by-step explanation:

The balanced chemical equation is option D:

4 Fe + 3 O₂ → 2 Fe₂O₃

This is a balanced equation because:

- There are four iron (Fe) atoms on both the reactant and product sides.

- There are three oxygen (O₂) molecules on both the reactant and product sides.

- The coefficients are the smallest possible integers that make the equation balanced.
