1: a: Nickel(II) Phosphate b: Iron(II) Iodide c: Manganese(III) Fluoride d: Chromium(II) Chloride e: (NaCN) Sodium Cyanide f: Copper(II) Sulfide 2: (I'm not entirely sure about this one) a: Arsenic Pentoxide b: (SiL4?) c: Phosphorus Trisulfide d: Phosphorus Decaoxide e: Selenium Dioxide f: Phosphorus Trichloride 3: The Roman numerals are part of the new style of compound nomenclature, to make better identification, because the older way was more confusing, partly because some element names are based on Latin or Greek names. (e.g. iron: Old: Ferrous, Ferric / New: Iron(II), Iron(III) ) MnO2 = Manganese(IV) Oxide Mn2O7= Manganese(VII) Oxide 4: Hexa- is prefix for 6. 5: 16.48% O 6: Cd2+. the cyanide ion has a charge of 1-, and there is 2 of them. 7: a: MgSO4 b: RbBr c: CrF2 d: Ni2CO3

There are two:- Iron II Sulphate FeSO4 and Iron III Sulphate Fe2(SO4)3. I can find no evidence for the existence of any iron sulphites as the only the alkali metal sulphites are commonly encountered.
