Iron metal can be oxidized to give ferric ion....

#Fe(s) rarr Fe^(3+) + 3e^(-)# #(i)#

And a typical oxidant would be dioxygen or dihalogen gas...e.g.

#1/2Cl_2(g) +e^(-) rarr Cl^(-)# #(ii)#

And so we add #(i) + 3xx(ii)#...

#Fe(s)+3/2Cl_2(g) +3e^(-) rarr Fe^(3+) + 3e^(-)+3Cl^(-)#

...to give finally...

#Fe(s)+3/2Cl_2(g) rarr FeCl_3(s)#
