Mg+HCl

When magnesium (Mg) reacts with hydrochloric acid (HCl), a chemical reaction occurs that produces magnesium chloride (MgCl2) and hydrogen gas (H2). The balanced equation for the reaction is:

Mg + 2HCl -> MgCl2 + H2

In this reaction, one mole of magnesium (Mg) reacts with two moles of hydrochloric acid (HCl) to produce one mole of magnesium chloride (MgCl2) and one mole of hydrogen gas (H2).

It is important to note that this reaction is highly exothermic, meaning it releases heat. It is also a single replacement reaction, where the magnesium (Mg) replaces the hydrogen (H) in the hydrochloric acid (HCl) to form the products.
