BaCl2+K2CrO4--------->BaCrO4+2KCl BaCrO4 is a yellow precipitate.
The reaction is:FeS2 + H2O + 3,5 O2 --------------- FeSO4 + H2SO4It is not a dissociation reaction.
The dissociation is:NaHCO3-------------Na+ + (HCO3)-
K2Cr2O7(aq) ------> 2K+(aq)+Cr2O72-(aq)
Pb(NO3)2----------Pb2+ + 2 (NO3)-
BaCl2+K2CrO4--------->BaCrO4+2KCl BaCrO4 is a yellow precipitate.
CaCl2 → Ca2+ and 2Cl-
The equation is: NaCl----------Na++ Cl-
Pb(C2H3O2) + K2CrO4 > PbCrO4
The reaction is:FeS2 + H2O + 3,5 O2 --------------- FeSO4 + H2SO4It is not a dissociation reaction.
The dissociation is:NaHCO3-------------Na+ + (HCO3)-
H2o --> h+ + oh-
NaCl------------>Na+ + Cl-
K2Cr2O7(aq) ------> 2K+(aq)+Cr2O72-(aq)
The equation is: H2O------>H+ + OH-
The equation is: H2O------>H+ + OH-
Pb(NO3)2----------Pb2+ + 2 (NO3)-
