2 Ag(s) + 2 HBr(aq) = 2 AgBr(aq) + H2(g)
Fe + O2 = Fe3O4 =>
3 Fe + 2 O2 = Fe3O4
KCrO{-}2 + AgNO3{-}1 = KNO3{-}1 + AgCrO{-}2 =>
KCrO{-}2 + AgNO3{-}1 = KNO3{-}1 + AgCrO{-}2
H3AsO3 + NaOH = NaH2AsO3 + H2O =>
H3AsO3 + NaOH = NaH2AsO3 + H2O
CH4 + Ni = Ni2C + H2 =>
CH4 + 2 Ni = Ni2C + 2 H2
MgCl2 + H2 = MgH2 + Cl2 =>
MgCl2 + H2 = MgH2 + Cl2
MgO + Na2O = MgNa + O =>
2 MgO + Na2O = 2 MgNa + 3 O
KHSeO4KOH = K2SeO4H2O =>
KHSeO4KOH = K2SeO4H2O
CaCO3 + HCl = CaCl2 + H2CO3 =>
CaCO3 + 2 HCl = CaCl2 + H2CO3
