H2SO4 is a tricky question and one that I would not know how to answer if I had to input to a computer. The first H is a strong electrolyte, the second one is weak (k1 ionizes 100%; k2 = about 10^-2).

FeCl2 ionizes 100%
HClO is a weak electrolyte
AgCl is a strong electrolyte BUT it isn't very soluble.
