WebIron sulfide, the compound formed in the reaction, has different properties to the elements from which it is made. The table compares the properties of iron, sulfur and iron sulfide: … WebIron sulfide oxidation reactions (mainly pyrite and pyrrhotite) tend to create an acidic environment, releasing protons, as observed in the oxidation reaction of pyrite in the presence of oxygen and water. The oxidative dissolution of pyrite is classically described as a two-stage reaction ( Singer and Stumm, 1970; Sanchez Espana, 2008 ):
WebYou need to test the hypothesis that: most iron sulfide is produced when equal molar amounts of iron and sulfur are used. This problem has been solved! You'll get a detailed solution from a subject matter expert that helps you learn core concepts. See Answer Question: Write an experimental protocol. The iron–sulfur world hypothesis is a set of proposals for the origin of life and the early evolution of life advanced in a series of articles between 1988 and 1992 by Günter Wächtershäuser, a Munich patent lawyer with a degree in chemistry, who had been encouraged and supported by philosopher Karl R. Popper to publish his ideas. The hypothesis proposes that early life may have formed on the surface of iron sulfide minerals, hence the name. It was developed by retrodiction (…
