Detailed information about the equation CaS + 3O2 -> CaSO4:
- CaS is the chemical formula for Calcium sulfide, a chemical compound that forms a white, odorless, and colorless solid.
- O2 is the chemical formula for oxygen, a chemical element with the symbol O and atomic number 8.
- CaSO4 is the chemical formula for Calcium sulfate, a colorless chemical compound, widely used in the industry.
-
Reaction conditions:
- The reaction requires high temperatures to perform, usually the temperature of a chemical furnace.
-
Reaction process:
- When calcium sulfide (CaS) reacts with oxygen (O2) under high-temperature conditions, it forms calcium sulfate (CaSO4).
- This reaction is a type of redox reaction, in which calcium sulfide is oxidized to calcium sulfate.
- 1 mol of Calcium sulfide reacts with 3 mol of oxygen to form 1 mol of calcium sulfate.
-
Observed phenomena:
- During the reaction, we can observe a color change, from the white color of calcium sulfide to the colorless of calcium sulfate.
- Also, the reaction releases heat so a temperature increase can be felt.
