The balanced chemical reactions of the following are:1. Iron (IIII) and copper (II) sulfate solution
2 Fe + 3 CuSO4 = 3 Cu + Fe2(SO4)3
2. Lead (II) nitrate and potassium iodide solutions
Pb(NO3)2 + 2 KI = 2 KNO3 + PbI2
3. Magnesium metal ribbon and hydrochloric acid solution
Mg + 2 HCl = MgCl2 + H2
4. Electrolysis of water
2 H2O = 2 H2 + O2
5. Burning magnesium
Mg + O2 = 2 MgO
Hope this answers the question. Have a nice day.
