Q

How do you figure out which roman numeral you would use in the example Fe2O3?

A
  1. Figure out if you know the charge of one of them : in this case we know oxygen has a -2 charge
  2. Look at the subscript: In this case oxygen has a 3 as the subscript
  3. Multiple the subscript by the charge of the known element: In this case it would be 2x3
  4. The answer you get is the LCM so now look at the subscript for the element with the unknown charge: in this case the subscript of iron is 2
  5. Now figure out what times the subscript equals the LCM: in this case it would be 3 because 3x2 is 6
  6. The number you come up with is the charge: In this case the charge of Fe would be 3 making this Iron(III)Oxide
