For every one iron atom in iron sulphide there is?

Answer 1

Sulfur atoms are not in iron atoms. Sulfur atoms combine with iron atom by accepting excess electrons from the iron atoms.

Iron atoms become iron ions with a positive charge. Sulfur atoms become sulfide ions with a negative charge. The opposite charges cause the oppositely charged ions to attract each other and form an ionic bond and, in the solid state, a crystal lattice structure.

Answer 2

Iron sulfide can take the form of FeS or Fe2S3 (very unstable), or several other varieties such as Fe3O4. Assuming you mean FeS, then the answer is as follows:
1 moles FeS contains 1 mole of Fe and 1 mole of Fe contains 6.02x10^23 atoms.
If you mean Fe2S3, then 1 mole contains 2 moles Fe which is 2 x 6.02x10^23 atoms = 1.2x10^24 atoms

Answer 3

Iron(II) sulfide is the chemical name for the molecular formula of FeS. The atomic ratios between each iron (Fe) and sulfur (S) atom in this molecule are 1:1.

Answer 4

one sulfur atom. Iron sulfide has a 1:1 ratio of iron atoms to sulfur atoms.

Answer 5

One Avogadro's number.

Answer 6

2 or 3
