650 ̊C.
» Common Magnesium compounds:
• Magnesium Hydroxide, Mg(OH)2
• Magnesium Oxide, MgO
• Magnesium Ammonium Phosphate Hexahydrate, MgNH4PO4.6H2O
• Magnesium Phosphate, Mg3(PO4)2
• Magnesium Nitrite, Mg(NO2)2
• Magnesium Sulfate, MgSO4
• Magnesium Chloride, MgCl2
Example Reactions:
• Mg + 2HCl = MgCl2 + H2
• Mg + O2 = MgO2
• Mg + H2SO4 = MgSO4 + H2
• 2K + MgBr2 = 2KBr + Mg
• Mg + CuSO4 = MgSO4 + Cu
• 2Na + MgF2 = 2NaF + Mg
• MgCl2 = Mg + Cl2
• Mg + Cu(NO3)2 = Mg(NO3)2 + Cu
• Mg + CuCl2 = MgCl2 + Cu
• Mg + 2HC2H3O2 = Mg(C2H3O2)2 + H2
