Question

1.Pb(NO3) --------PbO +NO2+O2
2.FeSO4--------Fe2O3+SO2+SO3
3.H2S+O2---------SO2+H2O
4.BaCl2+Al2(SO4)3--------AlCl3+BaSO4

,balance the equation

Answer 1

2Pb(NO3)2 ---------- 2PbO + 4NO2 + O2
2FeSO4 -------- Fe2O3 + SO2 + SO3
2H2S +3O2 ------- 2SO2 + 2H2O
3BaCl2 + Al2(SO4)3 ------- 2AlCl3 +3 BaSO4

Answer 2

i think your first question is wrong.
