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 CH2Cl2 (dichloromethane) reacts with Se (Selenium; C.I.77805; Se) and produce HCl (hydrogen chloride) and CSe2 (Carbon diselenide; Methanediselone)
This equation does not have any specific information about phenomenon.
In this case, you just need to observe to see if product substance CSe2 (Carbon diselenide; Methanediselone), appearing at the end of the reaction.
Or if any of the following reactant substances Se (Selenium; C.I.77805; Se), disappearing
We no further information about this chemical reactions.
