Answer:

2Fe + 3Cl2 → 2FeCl3

Explanation:

Fe + Cl2 —> FeCl3

There are 3atoms of Cl on the right side and 2 atoms on the left side. Therefore, to balance Cl put 2 in front of FeCl3 and put 3 in front of Cl2 as shown below:

Fe + 3Cl2 → 2FeCl3

Now, we see clearly that there are 2 atoms of Fe on the right side and 1 on the left side. This can be balanced by putting 2 in front of Fe as shown below:

2Fe + 3Cl2 → 2FeCl3

Now the equation is balanced.
