Question

Write a balanced equation for the reaction that occurs when a piece of magnesium is dropped into hydrochloride acid (HCI) solution forming magnesium chloride (MgCl2) in aqueous state and hydrogen gas

Answer 1

The balanced chemical equation is:

Mg_((s))+ 2HCl_((aq))rarrMgCl_(2(aq)) + H_(2(g)

Step-by-step explanation:

The reaction between magnesium and hydrochloric acid combine to form a salt of magnesium chloride and release hydrogen gas. This single replacement reaction is a classic example of a metal reacting in an acid to release hydrogen gas.
