i. diiron trioxide j. iron monoxide k. iron (iii) oxide l. iron (ii) oxide
m. iron (i) oxide n. sally smith

Explanation:

1. In $Fe_2O_3$, iron has a +3 oxidation state, so it is iron(III) oxide.
2. In $FeO$, iron has a +2 oxidation state, so it is iron(II) oxide.
3. In $Au_2O$, gold has a +1 oxidation state, so it is gold(I) oxide.
4. In $Au_2O_3$, gold has a +3 oxidation state, so it is gold(III) oxide.

Answer:

1. K. iron (III) oxide
2. L. iron (II) oxide
3. F. gold (I) oxide
4. E. gold (III) oxide
