give the net ionic equation for the reaction (if any) that occurs when aqueous solutions K2S and Fe(NO3)2 are mixed...Sooooo......K2S + Fe(NO3)2----> ?????? K2(NO3)2 +FeS2?? I really need help figuring out if this last part is right I don't understand is the subscript 2 after no3 the charge? the number of atoms? please help
