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.
K reacts with S
In a full sentence, you can also say K (potassium) reacts with S (sulfur) and produce K2S (potassium sulfide)
This equation does not have any specific information about phenomenon.
In this case, you just need to observe to see if product substance K2S (potassium sulfide), appearing at the end of the reaction.
Or if any of the following reactant substances S (sulfur), disappearing
We no further information about this chemical reactions.
potassium2H2O + 2K + CuSO4 → Cu(OH)2 + H2 + K2SO4 2H2O + 2K → H2 + 2KOH I2 + 2K → 2KI View all equations with K as reactant
sulfurFe + S → FeS H2 + S → H2S Cu + S → CuS View all equations with S as reactant
