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

Uk,lên gg thì nó là thế nhưng cứ cho là SO3 pu H2O)

Hehe GG toàn mấy từ TA ko ak khó đọc vãi_______________________________________________________
2H20 + 2K -->2KOH + H2_____________________________________________________________

 

[phankyanhls2000]

Koh+co2--->khco3

2khco3 + h2so4 -> k2so4 + 2h2co3__________________________________________________________________

 

[quynhphamdq]

$4h2 + k2so4 --> 4h2o + k2s$________________________________________________________

 

[thanhcong1594]

2FeCl3 + 3K2S => Fe2S3 + 6KCl____________________________________________________________

 

[lp_qt]

$ KCl + AgNO_3 \rightarrow AgCl + KNO_3$

 

[quynhphamdq]

2AgCl ->2Ag + Cl2_________________________________________________________________

 

[phankyanhls2000]

Cl2+Fe--->FeCl3
..........................

[thanhcong1594]

Sai rùi chú ơi______________________________________________________________________________________

 

[quynhphamdq]

3Cl2 + 2Fe -> 2FeCl3 .
(này ms đúng)!________________________________________________

 

[phankyanhls2000]

Ko cần cân bằng đâu mấy thím ạ.............................................

 

[thanhcong1594]

Vãi cả cái team_________________________________________________________________________________________

 

[thanhcong1594]

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

 

[nom1]

3Cl2 + 2Fe -> 2FeCl3 .
(này ms đúng)!________________________________________________

FeCl3 + NaOH -> Fe(OH)3 + NaCl
................................................

 

[phankyanhls2000]

NaCl--dp-->Na+Cl2
..............................
..............................

 

[quynhphamdq]

Ca + Cl2 -> CaCl2________________________________________________________________________________

 

[thanhcong1594]

Fe2 + CaCl2 => Fe(Cl2)3 + Ca _________________________________________________________________________

 

[phankyanhls2000]

Fe2 + CaCl2 => Fe(Cl2)3 + Ca _________________________________________________________________________

PT gì đây....................................................
Cái này chắc chắn sai rồi)

 

[thanhcong1594]

CaCl 2 + 2 KOH => Ca (Oh) 2 + 2 KCl___________________________________________________________________
