CaS + Cu(NO3)2 = Ca(NO3)2 + CuS
C5H11OH + KBr + H2SO4 = K2SO4 + C5H11Br + H2O =>
2 C5H11OH + 2 KBr + H2SO4 = K2SO4 + 2 C5H11Br + 2 H2O
I + AlCl3 = ICl + Al =>
3 I + AlCl3 = 3 ICl + Al
Li + HI = LiI + H2 =>
2 Li + 2 HI = 2 LiI + H2
Ca(HCO3)2 + Ca(OH)2 = Ca(CO3) + H2O =>
Ca(HCO3)2 + Ca(OH)2 = 2 Ca(CO3) + 2 H2O
CH3COOH + Na2S = CH3S + Na2COOH =>
CH3COOH + Na2S = CH3S + Na2COOH
Zn(NO3)2 + PbCl4 = ZnCl2 + Pb(NO3)4 =>
2 Zn(NO3)2 + PbCl4 = 2 ZnCl2 + Pb(NO3)4
CH2O + CuSO4 + NaOH = CHOOH + Cu2O + Na2SO4 + H2O =>
CH2O + 2 CuSO4 + 4 NaOH = CHOOH + Cu2O + 2 Na2SO4 + 2 H2O
