1) НСl + NaOH; 2) HNO3 + NH4OH; 3) HCl + Ba(OH)2; 4) H2SO4 + Ca(OH)2; 5) HF + KOH; 6) H2SO4 + Na2CO3; 7) CH3COOH + NH4OH; 8) HNO2 + NH4OH; 9) H2S + NH4OH; 10) Fe(OH)3 + HNO3.

1) НСl + NaOH = NaCl + H2O; 2) HNO3 + NH4OH = NH4NO3 + H2O; 3) 2HCl + Ba(OH)2 = BaCl2 + 2H2O; 4) H2SO4 + Ca(OH)2 = CaSO4 + 2H2O; 5) HF + KOH = KF + H2O; 6) H2SO4 + Na2CO3 = Na2SO4 + H2O + CO2; 7) CH3COOH + NH4OH = CH3COONH4 + H2O; 8) HNO2 + NH4OH = NH4NO2 + H2O; 9) H2S + 2NH4OH = (NH4)2S + 2H2O; 10) Fe(OH)3 + 3HNO3 = Fe(NO3)3 + 3H2O
