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.
Mix a small amount of magnesium oxide powder and coal powder, then place in the bottom of a dry test tube, heat
At high temperatures, carbon can reduce some metal oxides such as CuO, PbO, ZnO, ... into Cu, Pb, Zn, ... In metallurgy, people use this property of carbon to prepare metals. Carbon cannot remove metal oxides such as Na2O, K2O, CaO, BaO, MgO, Al2O3

Pass the ammonia gas through a glass tube containing heated magnesium oxide
Beside being a weak base, ammonia also exhibits reducing property. When heated, ammonia can reduce some metal oxides into metals (except the oxides of sodium, potassium, barium, calcium, magnesium)
