急求20个中和反应化学方程式!
要配平的,
答
NaOH+HCl--->NaCl+H2O
NaOH+HBr--->NaBr+H2O
NaOH+HI--->Nal+H2O
NaOH+HNO3--->NaNO3+H2O
2NaOH+H2SO4--->Na2SO4+2H2O
KOH+HCl--->KCl+H2O
KOH+HBr--->KBr+H2O
KOH+HI--->Kl+H2O
KOH+HNO3--->KNO3+H2O
2KOH+H2SO4--->K2SO4+2H2O
Ba(OH)2+2HCl--->BaCl2+2H2O
Ba(OH)2+2HBr--->BaBr2+2H2O
Ba(OH)2+2HI--->Bal2+2H2O
Ba(OH)2+2HNO3--->Ba(NO3)2+2H2O
Ba(OH)2+H2SO4--->BaSO4+2H2O
Ca(OH)2+2HCl--->CaCl2+2H2O
Ca(OH)2+2HBr--->CaBr2+2H2O
Ca(OH)2+2HI--->Cal2+2H2O
Ca(OH)2+2HNO3--->Ca(NO3)2+2H2O
Ca(OH)2+H2SO4--->CaSO4+2H2O
NH3.H2O+HCl--->NH4Cl+H2O
NH3.H2O+HBr--->NH4Br+H2O
NH3.H2O+HI--->NH4l+H2O
NH3.H2O+HNO3--->NH4NO3+H2O
2NH3.H2O+H2SO4--->(NH4)2SO4+2H2O
