directions: drag the answers to the correct boxes. balance the following equation using the lowest possible…

Explanation:

Step1: Balance oxygen atoms

We have 2 oxygen atoms in (O_2) and 3 oxygen atoms in (Fe_2O_3). The least - common multiple of 2 and 3 is 6. So we put a 3 in front of (O_2) and a 2 in front of (Fe_2O_3): (Fe + 3O_2\rightarrow2Fe_2O_3).

Step2: Balance iron atoms

Now, since we have 4 iron atoms on the right - hand side ((2Fe_2O_3)), we put a 4 in front of (Fe) on the left - hand side. The balanced equation is (4Fe+3O_2\rightarrow2Fe_2O_3).

Answer:

4, 3, 2
