✔ 最佳答案
Pb = Pb2+ + 2e- ( oxidation)PbO2 + 4 H+ + 2e- = Pb2+ + 2 H2O ( reduction)
Pb + PbO2 + 4 H+ = 2 Pb2+ + 2 H2O
add the spectator ion ( SO42-) to get the molecular balanced equation
Pb + PbO2 + 2 H2SO4 = 2 PbSO4 + 2 H2O

You wrote a complete mess up. The correct equation is: NaCl + PbSO4 ----> Na2SO4 + PbCl and the balanced equation is 2NaCl + PbSO4 ----> Na2SO4 + PbCl2
