The reaction is:FeS2 + H2O + 3,5 O2 --------------- FeSO4 + H2SO4It is not a dissociation reaction.
Pb(NO3)2----------Pb2+ + 2 (NO3)-
Hno3 -----------h+ + (no3)-1
The dissociation is:CaCl2------------------Ca(2+) + 2 Cl-
2K + 2H2O --> 2KOH + H2 The balanced equation shows that there is a 2 in front of water.
H2o --> h+ + oh-
The equation is: NaCl----------Na++ Cl-

Phosphine is not very soluble in water compared to nonpolar substances. If you were to write a balanced equation for the reaction of PH3 with water, it would be an equilibrium reaction.

Chromium don't react with water.
