I noticed a posting earlier on the board stating that H(NO2) weakly dissociates because it is considered to be a weak acid.  My question (sorry it is difficult to word correctly)

HCl, HBr, Hl, HClO4, HNO3, H2SO4 are the only compounds that will fully dissociate in water.  Does this mean that anything else containing H and _____ will weakly dissociate? 

eg) 3H2S will not dissociate because it is weak?

eg) H20 will not break apart because it is simply water in water?

Thanks

HCl, HBr, Hl, HClO4, HNO3, H2SO4

are considered as strong in college chemistry. For H2SO4 it is not true assumption (but for diluted solution it is a quite good approximation).
All other compound you mensioned are weak acids. In water solutions water itself is considered as a weakest acid and as a weakest base simultaneously.
 There are also much more stronger acids - see wikipedia - superacids
