Hydrogen gas and iron chloride are produced.
Explanation:
When dilute hydrochloric acid is added to iron fillings, then the iron reacts with HCl to release hydrogen gas and form iron chloride in an aqueous solution. This is a displacement reaction.
As soon as the acid is added, there will be a period of rapid bubbling. The bubbles are because the hydrogen gas is escaping. You can then find a thin layer of iron (III) chloride is formed.
Please refer to the attached picture for a balanced equation of this chemical reaction.
