Answer:

#"Copper(I) sulfide"-="cuprous sulfide"-=Cu_2S#

Explanation:

Copper metal can access two common oxidation states, i.e. #Cu^+# or #Cu^(2+)#:

#underbrace(Cu_2S)_"copper(I) sulfide or cuprous sulfide"#;

#underbrace(CuS)_"copper(II) sulfide or cupric sulfide"#.

As are most sulfide salts, both salts would be as soluble as bricks in aqueous solution, and are poorly characterizable...
