balance this equation: _fe + _o2 -> _fe2o3 drag these tiles and drop them in the correct blank above 4 1 2 0 3

Answer:

4 Fe + 3 O₂ → 2 Fe₂O₃

Explanation:

Step1: Balance oxygen atoms

We have 2 oxygen atoms in O₂ and 3 oxygen atoms in Fe₂O₃. The least - common multiple of 2 and 3 is 6. So we put a 3 in front of O₂ and a 2 in front of Fe₂O₃: Fe+3O₂→2Fe₂O₃.

Step2: Balance iron atoms

Now, on the right - hand side, we have 4 iron atoms in 2Fe₂O₃. So we put a 4 in front of Fe on the left - hand side: 4Fe + 3O₂→2Fe₂O₃.
