P2O5 + H2O ---> H3PO4 => P2O5 + 3H2O -> 2H3PO4

CaO + HNO3 ---> Ca(NO3)2 + H2O => CaO +2HNO3 -> Ca(NO3)2+H2O

N2O5 + H2O ---> HNO3 => N2O5 + H2O -> 2HNO3

Na2O + H2O ---> NaOH => Na2O +H2O -> 2NaOH

Al + CuO ---> Al2O3 + Cu => 2Al + 3CuO -> Al2O3 + 3Cu

K + HCl ---> KCl +H2 => 2K + 2HCl -> 2KCl + H2

Al + CuSO4 ---> Al2(SO4)3 + Cu => 2Al + 3CuSO4 -> Al2(SO4)3 + 3Cu

Al + H2SO4 ---> Al2(SO4)3 +H2 => 2Al + 3H2SO4 -> Al2(SO4)3 + 3H2

KOH + H2SO4 ---> K2SO4 +H2O => 2KOH + H2SO4 -> K2SO4 + 2H2O

Fe(OH)2 + HCl ---> FeCl2 + H2O => Fe(OH)2 + 2HCl -> FeCl2 + 2H2O

Al + HCl ---> AlCl3 + H2 => 2Al + 6HCl -> 2AlCl3 + 3H2

AlCl3 + Ca(OH)2 ---> Al(OH)3 + CaCl2 => 2AlCl3 + 3Ca(OH)2 -> 2Al(OH)3 + 3CaCl2

CH4 + O2 ---> H2O + CO2 => CH4 + 2O2 -> 2H2O + CO2

Fe2(SO4)3 + KOH ---> Fe(OH)3 + K2SO4 => Fe2(SO4)3 + 6KOH -> 2Fe(OH)3 + 3K2SO4
