Most kids love peanut butter. It is versatile and can go with many types of foods, such as apples, celery, crackers and bread. Peanut butter is high in fat, but it is monounsaturated fat that is considered heart healthy. Eating a couple of tablespoons as part of a meal or snack provides protein, an essential nutrient for growing kids.
Pyrite remains in commercial use for the production of sulfur dioxide, for use in such applications as the paper industry, and in the manufacture of sulfuric acid. Thermal decomposition of pyrite into FeS (iron(II) sulfide) and elemental sulfur starts at ; at around p S 2 is about .
It is not iron(IV) sulfide; the iron is in a +2 oxidation state, combined with an S 2 2- ion (the sulfur analog of the peroxide ion). Pyrite burns when heated to form sulfur dioxide and iron(III) oxide: The reaction is sometimes used in industry as a source of sulfur dioxide for the manufacture of sulfuric acid.he same pigment can be obtained from the reaction of iron(II) with ferricyanide: The product of the reaction is the blue color ingredient in many artist's pigments, printing inks, and dyes (including Berlin blue, Chinese blue, mineral blue, Paris blue, and Prussian blue).
