6 KI + 2 K2Cr3O7 + 14 H2SO4 = 5 K2SO4 + 3 Cr2(SO4)3 + 3 I2 + 14 H2O
AlCl3 + AgNO3 = AgCl + Al(NO3)3 =>
AlCl3 + 3 AgNO3 = 3 AgCl + Al(NO3)3
Cu(OH)2 + HNO3 = Cu(NO3)2 + H2O =>
Cu(OH)2 + 2 HNO3 = Cu(NO3)2 + 2 H2O
NaOH + H3PO4 = Na3PO4 + H2O =>
3 NaOH + H3PO4 = Na3PO4 + 3 H2O
Zn + HCI = ZnCI + H2 =>
2 Zn + 2 HCI = 2 ZnCI + H2
CaO + HOH = CaOH + OH =>
CaO + HOH = CaOH + OH
(NaHCO3) = Na2O + H2O + CO2 =>
2(NaHCO3) = Na2O + H2O + 2 CO2
C6H6 + O2 = CO + H2O =>
2 C6H6 + 9 O2 = 12 CO + 6 H2O
NH4Cl + Ca(OH)2 = CaCl2 + NH3 + H2O =>
2 NH4Cl + Ca(OH)2 = CaCl2 + 2 NH3 + 2 H2O
Al2O3 = Al + O2 =>
2 Al2O3 = 4 Al + 3 O2
PO4(aq) + H2O = H3PO4 + HO =>
PO4(aq) + 3 H2O = H3PO4 + 3 HO
