K2Cr2O7(aq) ------> 2K+(aq)+Cr2O72-(aq)
K2Cr2O7+14HCl ---> 3Cl2 + 2CrCl3 + 2KCl + 7H2O
The reaction is:FeS2 + H2O + 3,5 O2 --------------- FeSO4 + H2SO4It is not a dissociation reaction.
The dissociation is:NaHCO3-------------Na+ + (HCO3)-
Pb(NO3)2----------Pb2+ + 2 (NO3)-
I think the reaction equation can be written as follows: K2Cr2O7 (aq) + BaCl2(aq) ------ BaCr2O7(s) + 2KCl(aq).
K2Cr2O7
K2Cr2O7+14HCl ---> 3Cl2 + 2CrCl3 + 2KCl + 7H2O
CaCl2 → Ca2+ and 2Cl-
The equation is: NaCl----------Na++ Cl-
The reaction is:FeS2 + H2O + 3,5 O2 --------------- FeSO4 + H2SO4It is not a dissociation reaction.
The dissociation is:NaHCO3-------------Na+ + (HCO3)-
H2o --> h+ + oh-
K2Cr2O7 + Na2C2O4 --> K2C2O4 + Na2Cr2O7
NaCl------------>Na+ + Cl-
The equation is: H2O------>H+ + OH-
The equation is: H2O------>H+ + OH-
Pb(NO3)2----------Pb2+ + 2 (NO3)-
