Help with state symbols and enthalpy

What would the state symbol for iron (II)chloride be and is the reaction exothermic or endothermic?
For the second picture, is the reaction endothermic?
Might be wrong but assuming that you're reacting Iron (ii) Chloride and Sodium just like that (not in any solution), I would assume that the Iron Chloride would be solid so it would be FeCl2(s)

However if the question specifies or suggests that the reaction is happening in solution or aqueous conditions, it would probably be FeCl2(aq)

I'd write down FeCl2(s) to be on the safe side though considering NaCl is also solid and if the reaction was in solution, it would be NaCl(aq) not NaCl(s) :cookie:

About it being exothermic or endothermic, that requires some research, Perhaps use a data book to find out? Or use Hess' Law? :colondollar:

Iron chloride would be aqueous.
Don't know if it's exo or endo.
But for the second picture your silver nitrate should have a 2 in front of it, not a 2 after the Ag and NO3 as they would cancel out.

What would happen if you dropped sodium metal into any aqueous solution? Na + H2O?

Then again, if you drop some solid sodium onto some solid iron(II) chloride, there might be some reaction, but it would be limited to the surface layers. Then again again, that would be mostly Na2O/NaOH, so more likely it wouldn't react at all.

Hmm, he did mention in the first picture that sodium chloride was solid so wouldn't iron chloride also be solid considering that NaCl is a soluble salt? :holmes:

But NaCl is the product whereas iron chloride is the reactant?

NaCl would dissolve if it was produced though :confused:
You wouldn't be able to detect it unless you dried the entire solution as it would have dissolved in solution (assuming that the reaction is happening in solution) therefore it can't have happened in solution because NaCl is a solid ... :holmes:

No I get why NaCl is solid, just not sure about FeCl.
