Question

Which chemical equation is balanced?

O A. Fe + O₂ → Fe2O3
O B. 2 Fe + 0₂ - > Fe₂O3
O C. 2 Fe + 3 0₂ Fe2O3
D. 4 Fe + 3 0₂ 2 Fe2O3

Answer 1

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.
