kondaur [170]

Answer:

4 Fe + 3 O₂ → 2 Fe₂O₃

Explanation:

Let's start with the oxygen.

Reactants - 2

Products - 3

What number do 2 and 3 have in common? 6.

Put a 3 in the reactants and a 2 in the products to balance the oxygen.

Fe + 3 O₂ → 2 Fe₂O₃

Now let's look at the iron.

Reactants - 1

Products - 4

Put a 4 in the reactants to balance the iron.

4 Fe + 3 O₂ → 2 Fe₂O₃

The equation is balanced. Hope that helps.
