MgOHCl + HCl = MgCl2 + H2O
N2 + MgO = Mg + N2O =>
N2 + MgO = Mg + N2O
Cr2*O3 + Al = Al2O3 + Cr =>
Cr2*O3 + 2 Al = Al2O3 + 2 Cr
Br2 + SO2 + H2O = H2SO4 + HBr =>
Br2 + SO2 + 2 H2O = H2SO4 + 2 HBr
ZnSO4 + K3PO4 = Zn3(PO4)2 + K2SO4 =>
3 ZnSO4 + 2 K3PO4 = Zn3(PO4)2 + 3 K2SO4
CaCl2 + H2O = Ca(ClO4)2 + H2 =>
CaCl2 + 8 H2O = Ca(ClO4)2 + 8 H2
S + Na2SO3 + H2O = Na2S2O3*5H2O(s) =>
S + Na2SO3 + 5 H2O = Na2S2O3*5H2O(s)
H2 + O2 = H2O =>
2 H2 + O2 = 2 H2O
Ag(s) + Fe(NO3)2(ac) = Fe(s) + AgNO3(ac) =>
2 Ag(s) + Fe(NO3)2(ac) = Fe(s) + 2 AgNO3(ac)
CaC2H2 = C2H2Ca =>
CaC2H2 = C2H2Ca
FeC2O4(H2O)2(s) + O2(g) = FeO(s) + H2O(g) + CO2(g) =>
2 FeC2O4(H2O)2(s) + O2(g) = 2 FeO(s) + 4 H2O(g) + 4 CO2(g)
Rb + RbOH = Rb2O + H2 =>
2 Rb + 2 RbOH = 2 Rb2O + H2
Pb(O2H2) + HCl = H2O + PbCl2 =>
Pb(O2H2) + 2 HCl = 2 H2O + PbCl2
