Explanation:

For $Fe_2(CO_3)_3$, iron has a +3 oxidation - state here and $CO_3^{2 - }$ is the carbonate ion, so it's iron(III) carbonate. For $Cr(NO_3)_3$, chromium has a +3 oxidation - state and $NO_3^-$ is the nitrate ion, so it's chromium(III) nitrate.

Answer:

Part E: Iron(III) carbonate
Part F: Chromium(III) nitrate
