Explanation: The ideal environmental conditions for a reaction, such as temperature, pressure, catalysts, and solvent. Catalysts are substances that speed up the pace (velocity) of a chemical reaction without being consumed or becoming part of the end product. Catalysts have no effect on equilibrium situations.
In a full sentence, you can also say CaO () reacts with HgS (mercury(ii) sulfide) and produce Hg (mercury) and CaS (Calcium sulfide; Oldhamite) and CaSO4 (calcium sulfate)
This equation does not have any specific information about phenomenon.
In this case, you just need to observe to see if product substance CaSO4 (calcium sulfate), appearing at the end of the reaction.
Or if any of the following reactant substances HgS (mercury(ii) sulfide), disappearing
We no further information about this chemical reactions.
