Pb + PbO2 + H2SO4 --> PbSO4 + H2O
I believe that there is a typo in the formula, because of the ionization state of the lead. In the reactant PbO2, each oxygen carries a -2 charge, so the Pb must be +4, but in the products, PbSO4 is the problem... The SO4 will carry a -2 charge, which means the lead must now be a +2, If the lead went from +4 to +2, it would have had to get 2 electrons from somewhere.... So, the equation is balanced if it is: PbO2 + 2H2SO4 ---> Pb(SO4)2 + 2H2O or: PbO + H2SO4 ---> PbSO4 + H2O
Fe2O3 + H2SO4
Br2 + 2H2O + SO2 = H2SO4 + 2HBr
2 k + h2so4 = k2so4 + h2

Br2 + 2H2O + SO2 = H2SO4 + 2HBr
Ca(OH)2 + H2SO4 >> CaSO4 + 2H2O
2 k + h2so4 = k2so4 + h2
yes, but an insoluble layer of pbso4 will form on the solid pbo, thus resulting in an incomplete reaction

Together they make ammonium sulfate and water.
299 H2SO4 + 10 K4Fe(CN)6 + 122 KMnO4 = 60 CO2 + 5 Fe2(SO4)3 + 188 H2O + 60 HNO3 + 162 KHSO4 + 122MnSO4
K2SO4 + Pbl2 are the reactants.
H2SO4+Hg
LiCl+H2SO4=LiHSO4+HCl
