very difficult chemistry question.  check details for it.....?

The difference between \n\n1) HCl-->.H(g)+.Cl(g)   and\n\n2) HCl(g)-->H^+^(g)+ Cl^-^(g)\n\nis that in equation 2, you have two charged species.  We know that a positively charged species likes to interact with a negetively charged species (coulombic effect), thus making them much harder to dissociate.  This is what your hint was trying to address.  \n\nIn the gas phase, there also do not exist any solvents or counterions to stabalize the charged products in reaction 2.  The only reason that NaCl dissociates in water is due to the dipole moment of water which helps stables the Na^+^ abd CL^-^ ions.  In the gas phase, these don't exist so you would be hard pressed to acheive equation 2.

H2 + Cl2 -> 2HCl\n2Ag + H2S -> Ag2S + H2 \nCH4 + 2O2 -> CO2 + 2H2O\n2HgO -> 2Hg + O2\n3Fe + 4H2O -> Fe3O4 + 4H2

This is a tricky question. Perhaps reading: http://www.newton.dep.anl.gov/askasci/chem03/chem03067.htm will help.

And this is chemistry how??

Hey I'm studying physical and chemical equilibrium too, currently.The answer is that it will definitely have units when the concentrations have different powers.Just try and work it out with the units and it will be very clear.

I think it is this:\n\n            \nC12H22O11(s) --- HNO3---->  12C(s) = 11H2O(g) + heat

Please do your own home work.\n\nI suspect you are missing a symbol, it probably should be,\nN2O4  <==>  2NO2\n\nThink about how each of the changes will effect the equilibrium of the reaction.

I HAVE A CHEMISTRY EXAM tomorrow. Actually a small test.lol\nwant answers go to the site below!

1. AgCl(s) + NaNO3\n\n2. AgOH(s) + NaNO3\n\n3. They would not react as both are nitrates already

The answer is c.\nC12H22O11+12O2-->12CO2+11H2O

My answer is,\n \nNH4NO3(ag) + KOH(aq) -> NH4OH(aq) + KNO3(aq)

IAnd for your other request, I would request you to send a seperate mail to me through yahoo Answer so that I am able to send it part by part.These are long subjects and would take some time,The balanced equation would be                                           H3PO4+3KOH=K3PO4+3H2O
