You couldn't find them, probably because there is no reason to get confused with the answers, at least for some of them. I would name them
sodium(I) chloride **see note
potassium(I) fluoride ** see note
calcium(II) sulfide **see note
cobalt(II) nitrate (could confuse)
iron(III) phosphate (could confuse)
mercury(II) sulfate (could confuse)
mercury(II) phosphate (could confuse)
**The I is not necessary because Na, K, and Ca are known only in the +1 or +2(for Ca) states. Frankly, I don't know if placing a I or II there is incorrect or not.
