Most importantly: the molecules in the equation should not be taken apart as you did! So keep them clustered as in the equation you start with:
From here it is a combination of common sense and trial and error:
Step 1 balance out the iron, leave the
Step2 then try to get the number of
Step3 now make the number of
Finally, check the equation and you'll see it is balanced now!
