At temperatures between 80–120°C (176-248°F), the iron sulfide catalyzed reactions in which molecular hydrogen reduced carbon ...

A greenish-grey ring around the yolk of a hard-boiled egg might cause concern. Is it a sign of spoilage or something else ...

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.

Previously, it had been considered that the temperature in the Martian core is likely too high for a solid inner core to crystallize, but the possibility of an iron-sulfide mineral forming the ...

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 ...

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 ...

Hydrogen sulfide in water causes no known health effects. However, high concentrations do change the taste of the water. Hydrogen sulfide dissolved in water corrodes metals such as iron, steel, copper ...

Infinity Mining Limited (ASX: IMI) is set to expand its exploration efforts at the Cangai Copper Project following the identification of magnetic pyrrhotite within the copper mineralization zone.
