Mình làm phương trình đầu tiên như vậy cũng ổn đúng hông bạn?
a) HCl(đ) + MnO2 -t0-> Cl2 + MnCl2 + H2O
b) CuO + 2HCl - > CuCl2 + H2O
c) 2HCl + Na2Co3 -> CO2 + 2NaCl + H2O
d) HCl + AgNO3 - > AgCl + HNO3
e) 2KCl + 2H2O \(\xrightarrow[cmn]{đpdd}\) 2KOH + Cl2 + H2
f) Cl2 + H2O - > HCl + HClO
Cl2 + NaOH - > NaCl + NaClo
g Cl2 + Ca(OH)2 -t0->CaoCl2 + H2O
h) 2CaOCl2+ H2O + CO2 - > CaCO3 + CaCl2 +2HClO
NaClo + CO2 + H2O - > NaHCO3 + HClO
