Question

What happens when diluted hydrochloric acid is added to iron fillings?

Answer 1

Here is your answer

HCl is a strong acid that reacts with metals to give hydrogen gas and salt.

And same thing will happen here also

Now, according to the question

2HCl+ Zn - - - > ZnCl2 + H2

Always remember while writing chemical equations balance both no. Of atoms of both sides to satisfy the law of conservation of mass.

Thanks

Answer 2

HCL will react with iron to form hydrogen gas and metal salts
