NaC2H3O2 --> Na+ + C2H3O2-
The reaction is:FeS2 + H2O + 3,5 O2 --------------- FeSO4 + H2SO4It is not a dissociation reaction.
The dissociation is:NaHCO3-------------Na+ + (HCO3)-
The equations are: H2O ↔ H+ + (OH)- 2H2O ↔ (H3O)+ + (OH)-
dissociation of acid in water: A + H2O <-> A- + H3O+ with dissociation constant Ka = [A-][H3O+]/[A][H2O] = [A-][H3O+]/[A]. dissociation of base in water: B + H2O <-> HB+ + OH- with dissociation constant Kb = [HB+][OH-]/[B][H2O] = [HB+][OH-]/[B] dissociation of water in itself: 2H2O <-> H3O+ + OH- with dissociation constant Kw = [H3O+][OH-]/[H2O]^2 = [H3O+][OH-] where [H2O] has been ommitted because it is a pure liquid. substituting relations for Ka and Kb into Kw gives: Kw = [H3O+][OH-] = (Ka[A]/[A-])(Kb[B]/[HB+]) = KaKb where [A] = [HB+] and [B] = [A-].
Na2O + H2O
H2o --> h+ + oh-
The reaction is:FeS2 + H2O + 3,5 O2 --------------- FeSO4 + H2SO4It is not a dissociation reaction.
The dissociation is:NaHCO3-------------Na+ + (HCO3)-
The equation is: H2O------>H+ + OH-
The equation is: H2O------>H+ + OH-
H2o
H2o
The equations are: H2O ↔ H+ + (OH)- 2H2O ↔ (H3O)+ + (OH)-
dissociation of acid in water: A + H2O <-> A- + H3O+ with dissociation constant Ka = [A-][H3O+]/[A][H2O] = [A-][H3O+]/[A]. dissociation of base in water: B + H2O <-> HB+ + OH- with dissociation constant Kb = [HB+][OH-]/[B][H2O] = [HB+][OH-]/[B] dissociation of water in itself: 2H2O <-> H3O+ + OH- with dissociation constant Kw = [H3O+][OH-]/[H2O]^2 = [H3O+][OH-] where [H2O] has been ommitted because it is a pure liquid. substituting relations for Ka and Kb into Kw gives: Kw = [H3O+][OH-] = (Ka[A]/[A-])(Kb[B]/[HB+]) = KaKb where [A] = [HB+] and [B] = [A-].
dihydrogen monoxide. not positive though.
Na2O + H2O
NaCl --> Na+ + Cl- You could write water on either side I suppose, but it is negligible. I've also seen H2O written over the arrow.
