Question

Describe what would happen if hydrochloric acid reacted with a metal, for example magnesium. Write a word equation for this reaction.

Answer 1

Explanations:

When hydrochloric acid reacts with a metal, it will produce the chloride of the metal involved and hydrogen gas will evolve (single replacement reaction).

If the metal is magnessium, the reaction between hydrochloric acid and magnesium is expressed as:

`2HCl(aq)+Mg(s)\rightarrow MgCl_2(aq)+H_2(g)`

The word equation is given as:

`hydrochloric\text{ acid}+magnesium\rightarrow magnesium\text{ choride}+hydrogen\text{ gas}`
