• CaO + H2O = Ca(OH)2

• NaOH + HCl = NaCl + H2O

• 2HCl + CaCO3 = CaCl2 + CO2 + H2O

• NaOH + H2SO4 = NaHSO4 + H2O

• CO2 + H2O = H2CO3

• Ca(H2PO4)2 + 2La(NO3)3 + H2O = 2LaPO4 + 6HNO3 + CaO

• HNO3 + NaHCO3 = NaNO3 + CO2 + H2O

• BaO + H2O = Ba(OH)2

• CH3CH2OH + O2 = H2O + CH3COOH

• NaH + H2O = NaOH + H2
