2Ca(OH)2 + Cl2 => 2H2O + CaCl2 + Ca(ClO)2 ________________________________________________________

$CaCl_2+CO_2+H_2O ----> CaCO_3 + 2HCl $

2CaCO3 + 2NaHSO4 => Ca2 + 2HCO3 + 2Na + 2SO4__________________________________________________________

 

[lp_qt]

2CaCO3 + 2NaHSO4 => Ca2 + 2HCO3 + 2Na + 2SO4__________________________________________________________

pt sai ==> lấy pt của hien_vuthithanh:

$4HCl_đ+ MnO_2 \overset{t^{\circ}}{\rightarrow} MnCl_2 + Cl_2 +2H_2O$

p/s:ko biết đúng ko

 

[thanhcong1594]

hình như là : H2S + 4H2O2 -->SO3 + 5H2O______________________________________________________________
