Question

How can u say that ferrous sulphide is a compound? What is it's chemical formula?​

Answer 1

Answer:

❚⠀ ⠀Iron(II) sulfide or ferrous sulfide (Br. E. sulphide) is one of a family chemical compounds and minerals with the approximate formula FeS. Iron sulfides are often iron-deficient non-stoichiometric.
