Calcium Sulfate is CaSO4 Express your answer as a chemical equation. CaS is produced by "carbothermic reduction" of calcium sulfate, which entails the conversion of carbon, usually as charcoal, to carbon dioxide: In the second reaction the sulfate (+6 oxidation state) oxidizes the sulfide (-2 oxidation state) to sulfur dioxide (+4 oxidation state), while it is being reduced to sulfur dioxide itself (+4 oxidation state). For example, we can predict that silver fluoride could be replaced by silver nitrate in the preceding reaction without affecting the outcome of the reaction. Students tend to think that this means they are supposed to just know what will happen when two substances are mixed. Reaction stoichiometry could be computed for a balanced equation.
