Answer

Answer:

C. 4Fe + 3O₂ -> 2Fe₂O₃

Explanation:

Step1: Check Fe atoms

On the left - hand side of 4Fe + 3O₂ -> 2Fe₂O₃, there are 4 Fe atoms. On the right - hand side, in 2Fe₂O₃, 2×2 = 4 Fe atoms.

Step2: Check O atoms

On the left - hand side, in 3O₂, there are 3×2=6 O atoms. On the right - hand side, in 2Fe₂O₃, 2×3 = 6 O atoms. So 4Fe + 3O₂ -> 2Fe₂O₃ is balanced. For option A: 2 Fe + 3O₂ -> Fe₂O₆, the product formula is incorrect as the correct formula for iron(III) oxide is Fe₂O₃ not Fe₂O₆. For option B: 4 Fe + O₆ -> 2Fe₂O₃, oxygen in nature exists as O₂ not O₆.
