K2co3 + h2so4 = co2 + h2o + k2so4
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

 

[tien_thientai]

K2co3 + h2so4 ---> co2 + h2o + k2so4
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

 

[phankyanhls2000]

K2SO4+BaCl2--->KCl+BaSO4
..............................................

 

[tien_thientai]

H2SO4 + BaSO4--->Ba(HSO4)2
P/s:Khó nói tiếp đây!!!
mn cố gắng nha

 

[thanhcong1594]

$Ba(HSO4)2 + 2NaHCO3 -------> BaSO4 + Na2SO4 + 2CO2 + 2H2O$_________________________________________

 

[tien_thientai]

2H2O+Ca--->Ca(OH)2+H2
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

 

[thanhcong1594]

$2h2 + o2 -->2h2o$_______________________________________________________________________________-

 

[tien_thientai]

2 KMnO4 + 3 Na2SO3 + H2O ---> 2 MnO2 + 3 Na2SO4 + 2 KOH

 

[thanhcong1594]

_______________________________$Ba(NO3)2 +Na2SO4 ------>2NaNO3 +BaSO4$

 

[tien_thientai]

3Cu + 2NaNO3 + 4H2SO4 ---> 3CuSO4 + 2NO + Na2SO4 + 4H2O

 

[phankyanhls2000]

No+o2--->no2

[thanhcong1594]

$H2S + CuSO4 => CuS + H2SO4$_____________________________________________________________________

 

[phankyanhls2000]

CuS+HCl--->CuCl2+H2S
.......................................
Lần sau phải nối đúng nha

 

[nom1]

CuS+HCl--->CuCl2+H2S
.......................................
Lần sau phải nối đúng nha

CuCl2 + AgNO3 -> Cu(NO3)2 + AgCl
....................................................

 

[thanhcong1594]

AgN03+HCl=>AgCl+HN03
P.s chậm 1 s______________________________________

 

[phankyanhls2000]

FeCl2+Cl2--to-->FeCl3
.....................................

 

[thanhcong1594]

3NaOH + FeCl3 => 3NaCl +Fe(OH)3 __________________________________________________________________________________

 

[phankyanhls2000]

Fe(OH)3--to-->Fe2O3+H2O
...........................................

 

[thanhcong1594]

$Fe2O3+6HCl => 2FeCl3+ 3 H2O$_________________________________________________________________

 

[hien_vuthithanh]

$Fe2O3+6HCl => 2FeCl3+ 3 H2O$_________________________________________________________________

$FeCl_3 + Al ------------->AlCl_3 + Fe $
