Temperature: temperature
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 HCl (hydrogen chloride) reacts with MnO2 (manganese dioxide) and produce Cl2 (chlorine) and H2O (water) and MnCl2 (manganese(ii) chloride)
The method is used to prepare chlorine gas in laboratories. Chlorine gas is produced by letting concentrated hydrochloric acid react with strongly oxidating substances MnO2.
