Answer:
2Fe + 3Cl_2 → 2FeCl 3
Step-by-step explanation:
To balance the equation, we need to make sure that the number of atoms of each element is the same on both sides of the equation. In this case, we have two iron atoms and six chlorine atoms on the left-hand side, and two iron atoms and six chlorine atoms on the right-hand side. To balance the equation, we can add a coefficient of 2 in front of FeCl3 to get:
2Fe + 3Cl_2 → 2FeCl 3
Now we have two iron atoms and six chlorine atoms on both sides of the equation, and the equation is balanced.
