3.2,11,1 Princivles-
Pyritic minerals begin to change into two new products when exposed to the
atmosphere. The change may proceed slowly over a long period of tine
before the final products (yellavboy and sulfuric acid) are formed. The
sad product, "yellawboy," actually may form only when the eulfnte is
partially or completely neutralized by a basic substance. The chemical
equation for this complete chmge in pyrite follows:
