Correspondence between salt formulas and their names:

The formula for a salt is determined by the combination of the cation (positively charged ion) and the anion (negatively charged ion) present in the salt. Here is the correspondence between the given salt formulas and their names:

1. CuCl: This formula represents copper(I) chloride. The cation is copper(I) (Cu+) and the anion is chloride (Cl-).

2. FeCl3: This formula represents iron(III) chloride. The cation is iron(III) (Fe3+) and the anion is chloride (Cl-).

3. FeSO4: This formula represents iron(II) sulfate. The cation is iron(II) (Fe2+) and the anion is sulfate (SO4^2-).

4. CuCl2: This formula represents copper(II) chloride. The cation is copper(II) (Cu2+) and the anion is chloride (Cl-).

5. FeS: This formula represents iron(II) sulfide. The cation is iron(II) (Fe2+) and the anion is sulfide (S^2-).

Therefore, the correspondence between the given salt formulas and their names is as follows:

A. FeSO4: Ferum (II) sulfate B. FeCl3: Ferum (III) chloride C. CuCl: Kuprum (I) chloride D. FeS: Ferum (II) sulfide E. CuCl2: Kuprum (II) chloride
