In the process, the real causes of the war were swept under the rug, the better to facilitate economic partnerships and sentimental reunions of Civil War veterans.
Science. Explain why iron sulphide is a compound and not just a mixture of the two elements iron and sulphur. Explain why iron sulphide has different properties to a mixture of iron and sulphur and also describe and explain tests that can distinguish between iron sulphide and a mixture of iron and sulphur.
Iron(II,III) sulfide is a blue-black (sometimes pinkish) chemical compound of iron and sulfur with formula Fe 3 S 4 or FeSÂ·Fe 2 S 3, which is much similar to iron(II,III) oxide.It occurs naturally as the sulfide mineral greigite and is magnetic. It is a bio-mineral produced by and found in magnetotactic bacteria.ike the related oxide magnetite (Fe 3 O 4), iron(II,III) sulfide is ferrimagnetic, with the spin magnetic moments of the Fe cations in the tetrahedral sites oriented in the opposite direction as those in the octahedral sites, and a net magnetization.
