Answer:
When dilute hydrochloric acid is added to iron fillings then ferrous chloride and hydrogen gas will be formed.
Explanation:
The reason behind this is that iron(Fe) is more reactive than hydrogen, therefore it displaces hydrogen from hydrochloric acid to form iron(II) chloride and hydrogen gas.This is a displacement reaction.
The equation for the above reaction is as follows:-
Fe(s)+2HCl(aq)-->FeCl2(aq)+H2(g)
