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.

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.

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 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 ...

Examples include chalcocite (copper sulfide), galena (lead sulfide), cinnabar (mercury sulfide), and pyrite (iron sulfide). Sulfates, where sulfur and oxygen bind with a cation, are also common ...

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.

Using sulfur as a resource, astronauts could build solar cells and batteries that use sulfur, mix up sulfur-based fertilizer and make sulfur-based concrete for construction.
