Answer: The products are sodium acetate
and solid silver chloride 
Explanation:
A double displacement reaction is one in which exchange of ions take place. The salts which are soluble in water are designated by symbol (aq) and those which are insoluble in water and remain in solid form are represented by (s) after their chemical formulas.
The reaction of aqueous solutions of sodium chloride and silver (I) acetate is :

Thus the products are aqueous sodium acetate
and solid silver chloride 
(A)Conductor permits the flow of electrons.
Answer: Every action force results in an equal and opposite reaction force.
Explanation: newtons law
The process that is occurring as iodine solid is transformed into iodine vapour is SUBLIMATION.
Sublimation is the process by which a substance transformed from a solid state straight into a gaseous state without passing through the liquid state. Iodine is capable of undergoing sublimation process and this property is usually used to separate iodine from mixtures.<span />
