The synthesis of iron (II) sulfide involves reacting 1 equivalent of sulfur with 1 equivalent of iron. The reaction is initiated by a hot glass stirring rod into it. It is an extremely exothermic ...

Iron sulfides, common in ancient hydrothermal vents, may have played a crucial role in creating life on Earth. These minerals could have helped form the basic molecules needed for life, new research ...

The question of where life on Earth began has long puzzled scientists, but new research suggests that ancient hot springs, similar to the ones in Yellowstone National Park, may have played a crucial ...
