  1. Practice Magnesium metal is burned in nitrogen Mg + N2Mg3N2 Lead foil is immersed in silver nitrate Pb + Ag+ Pb 2+ + Ag A solution of ammonium sulfate is added to a saturated solution of barium hydroxide NH4++ SO2++ Ba2++ OH-BaSO4+ NH3+ H2O Acetic acid is added to a solution of sodium hydrogen carbonate HC2H3O2 + HCO31-H2O + CO2

  2. Solid sodium dichromate is added to an acidified solution of sodium iodide Na2Cr2O72- + I-  Cr3+ + I2 + Na+ Ethanol is completely burned in air CH3CH2OH + O2 CO2 + H2O Hydrogen gas is passed over hot iron III oxide H2 + Fe2O3 Fe + H2O Solutions of potassium iodide and potassium iodate are mixed in an acid solution I- + IO3-  I2

  3. Dilute sulfuric acid is added to solid calcium fluoride H+ + HSO4- + CaF2CaSO4 + HF Solid ammonium carbonate is heated (NH4)2CO3  NH3 + H2O + CO2 Hydrogen peroxide is added to an acidified solution of sodium bromide H2O2 + Br-H2O + Br2 Dilute hydrochloric acid is added to a dilute solution of mercury I nitrate Cl- + Hg22+ Hg2Cl2

  4. Dilute sulfuric acid is added to lithium hydrogen carbonate H+ + HCO3- CO2 + H2O Solid calcium is added to warm water Ca + H2O  Ca2+ + OH- + H2 Hydrogen sulfide is bubbled through a solution of nickel II nitrate H2S + Ni2+ NiS + H+

  5. Excess sodium hydroxide is added to solid aluminum hydroxide Al(OH)3 + OH-  [Al(OH)4]- Solid silver is added to a dilute (6M) nitric acid solution Ag + H+ + NO3-  Ag+ + NO + H2O Excess potassium hydroxide is added to a solution of potassium dihydrogen phosphate OH- + H2PO4-  H2O + PO43- Hydrogen peroxide solution is added to a solution of iron II sulfate H2O2 + Fe2+  H2O + Fe3+

  6. Propanol is burned completely in air CH3CH2CH2OH + O2  CO2 + H2O Solid potassium chlorate is heated in the presence of a catalyst, Manganese IV oxide MnO2 KClO3  KCl + O2 THE END
