10 NiSO4 + 2 KMnO4 + 8 H2SO4 = 5 Ni2(SO4)3 + 2 MnSO4 + K2SO4 + 8 H2O
HCl + KOH = H2O + KCl =>
HCl + KOH = H2O + KCl
Mg + (CO3)2 = MgCO3 =>
2 Mg + (CO3)2 = 2 MgCO3
H2SO4 + RbOH = Rb2SO4 + H2O =>
H2SO4 + 2 RbOH = Rb2SO4 + 2 H2O
COCl2 + NaOH = CO(OH)2 + NaCl =>
COCl2 + 2 NaOH = CO(OH)2 + 2 NaCl
P2O5 + H2O = H2O2 + POH =>
P2O5 + 5 H2O = 4 H2O2 + 2 POH
N2H4(l) + H2O2(l) = HNO3(aq) + H2O(l) =>
N2H4(l) + 7 H2O2(l) = 2 HNO3(aq) + 8 H2O(l)
Cs(s) + HBr(aq) = CsBr(aq) + H2(g) =>
2 Cs(s) + 2 HBr(aq) = 2 CsBr(aq) + H2(g)
Fe + O2 = Fe2O3 =>
4 Fe + 3 O2 = 2 Fe2O3
KMnO4 + HCl + H2SO4 = MnSO4 + K2SO + Cl2 + H2O =>
2 KMnO4 + 16 HCl + 3 H2SO4 = 2 MnSO4 + K2SO + 8 Cl2 + 11 H2O
