The film discusses the classification of matter into homogeneous and heterogeneous types, focusing on elements, compounds, and mixtures. It explains the properties of two elements, iron and sulfur ...

A mixture of iron filings and sulfur powder could be separated in exactly the same way. Image caption, A magnet separating iron filings from sulfur powder. Back to top. Filtration.

Wrought iron consists primarily of iron with 1 to 2% of added slag, which is the byproduct of iron ore smelting, and is a mix of silicon, sulfur, phosphorous, and aluminum oxides.

As the molten, iron-sulfur mixture in the outer core slowly cools, iron atoms condense into cubic "flakes" that fall toward the planet's center, Chen said.

Pure iron begins to solidify below 2,800 degrees Fahrenheit, but the right iron-sulfur mix can remain liquid at temperatures as low as 1,810 degrees Fahrenheit.

As it happens naturally at the seafloor, iron and sulfur geochemical reactions took place at high temperatures, forming iron sulfide minerals such as mackinawite (FeS) and greigite (Fe 3 S 4) in a ...

They created a molten iron and sulfur mixture—similar to Mercury's core. They subjected the mix to high temperatures and pressures. Then they analyzed what happened in this Mercury model.
