Scientists have identified another possible commonality between Earth and Mars: a solid inner core. Scientists have ...

Geochemical evidence from laboratory experiments for a potential solid inner core at the center of Mars is reported in Nature ...

This article contains major spoilers from “The Man Who Kept The Secrets,” the Season 1 finale of “Paradise,” now streaming on ...

Sulfur, in the form of iron sulfide, can cause steel to be too porous and prone to cracking. Atomic number 16, atomic weight 32.064. Silicon (Si): Silicon is the second most abundant element in ...

Chemical composition of ancient rocks Iron sulfide can only exist in rocks that were formed before there was oxygen in the atmosphere. Rocks containing iron oxide can only form if oxygen is present.

However, high concentrations do change the taste of the water. Hydrogen sulfide dissolved in water corrodes metals such as iron, steel, copper and brass. The corrosion of iron and steel from sulfur ...

The iron can no longer be removed by a magnet because it’s bonded to the sulfur. Iron sulfide, a new substance, has been formed because the iron and sulfur atoms are now chemically bonded together.

3). Whereas most magnetite-producing magnetotactic bacteria occur in a water column's oxic-anoxic transition zone, most iron-sulfide-producing magnetotactic bacteria occur in the anaerobic zone ...
