Other Condition: at high 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.
Lead the steam into a test-tube containing 1 mL of mercury metal.
In a full sentence, you can also say H2O (water) reacts with Hg (mercury) and produce H2 (hydrogen) and HgO ()
+ The metals with strong reducing properties such as Na, K, Ca, ... dehydrate easily at normal temperature. + Some metals with average reducing properties such as Zn, Fe, ... can reduce water vapor at high temperatures. + The metals with weak reducing properties such as Cu, Ag, Hg, ... cannot reduce water, even at high temperatures.
waterCaO + H2O → Ca(OH)2 2H2O + 2K + CuSO4 → Cu(OH)2 + H2 + K2SO4 2H2O + 2NaCl → Cl2 + H2 + 2NaOH View all equations with H2O as reactant
