Calcium sulfide can be prepared by the direct reaction of the elements, calcined in an inert atmosphere, at a 1:1.05 molecular ratio: Ca+S+heat→CaS This white material crystallizes in a cubic structurelike rock salt and the bonding is highly ionic. This is consistent with its description as...
yields calcium sulfide (CaS), which adds additional sulfur to give polysulfides, such as CaS2and CaS4. Calcium reacts with dry hydrogen at 300°-400°C to give the hydride CaH2, an ionic compound in which hydrogen is the anion. Calcium and nitrogen react at 500°C to give the nitride ...
Forumula of ionic compounds. How can I figure those out? Write the correct formula for manganese(IV) oxide. Is it a molecular or ionic compound? Write the formula for each of the following ionic compounds?\a) nickel(III) oxide b) Iron(III) sulfide c) lead(II) sul...

With increasing hydration degree of the slag, sulfide ions are released into the pore solution, which can be used as a semi-quantitative indicator of slag dissolution. Si and Al concentrations in the pore solution are generally low, depending on the pH value of the pore solution, and increase...
Anhydrous calcium chloride is a dehydrating agent and desiccant commonly used in industrial production and laboratories (but cannot dry ammonia, hydrogen sulfide and alcohol). It is mainly used for drying gases, petroleum, organic solvents, etc., inorganic industry It is used as a raw material for...
Therefore, it exists in the form of ion or compound in nature. Chemical property Most non-metals react directly with heating, such as with sulfur, nitrogen, carbon, hydrogen reaction to calcium sulfide CaS, calcium nitride Ca3N2, calcium carbide CaC2 and calcium hydrogen CaH2, heating ...
The largest use of metallic calcium is in steelmaking, due to its strong chemical affinity for oxygen and sulfur. Its oxides and sulfides, once formed, give liquid lime aluminate and sulfide inclusions in steel which float out; on treatment, these inclusions disperse throughout the steel and bec...
