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 H2O (water) reacts with K2CO3 (potassium carbonate) reacts with CO2 (carbon dioxide) and produce KHCO3 (potassium hydrogencarbonate)
This equation does not have any specific information about phenomenon.
In this case, you just need to observe to see if product substance KHCO3 (potassium hydrogencarbonate), appearing at the end of the reaction.
Or if any of the following reactant substances CO2 (carbon dioxide), disappearing
To separate H2 from CO, they use K2CO3 absorbing CO2 at high pressure
water2H2O + 2KMnO4 + 5SO2 → 2H2SO4 + 2MnSO4 + K2SO4 2H2O + 2K + CuSO4 → Cu(OH)2 + H2 + K2SO4 2H2O → 2H2 + O2 View all equations with H2O as reactant
potassium carbonateK2CO3 + MgSO4 → MgCO3 + K2SO4 K2CO3 + 2NaHSO4 → H2O + Na2SO4 + K2SO4 + CO2 K2CO3 + 2NH4NO3 → H2O + 2KNO3 + 2NH3 + CO2 View all equations with K2CO3 as reactant
carbon dioxideC + CO2 → 2CO 2NH3 + CO2 → (NH2)2CO + H2O H2O + CO2 → H2CO3 View all equations with CO2 as reactant
