In the copper(I) sulfide, the copper is +1 and the sulfur -2. The oxidation states of the elements oxygen (in the gas) and copper (in the metal) are 0. In sulfur dioxide, the oxygen has an oxidation state of -2 and the sulfur +4. That means that both the copper and the oxygen have been reduced (decrease in oxidation state).Web

List Sulphide Minerals. The sulphide minerals are compounds of the metals with sulphur. Nearly all these minerals have a metallic luster, i.e., the peculiar shining appearance of metals, such as gold, silver, copper, lead, tin, iron, etc. They are all heavy minerals and nearly all are of economic importance.Web

Vulcanizing agents other than sulfur are peroxides, resins and metal oxides used to form cross-links in the rubber [30]. Unsaturated elastomers (C=C) can be vulcanized with sulfur, while the saturated elastomers (C-C) cannot be vulcanized with sulfur but are vulcanized by peroxides. The cross-linking reactions mainly occur at the C=C bonds.Web
