Here's why:
* Single displacement reactions involve one element replacing another element in a compound.
* In this case, magnesium (Mg) is more reactive than hydrogen (H).
* Magnesium displaces hydrogen from hydrochloric acid (HCl), forming magnesium chloride (MgCl₂) and releasing hydrogen gas (H₂).
The balanced chemical equation for this reaction is:
Mg(s) + 2HCl(aq) → MgCl₂(aq) + H₂(g)
Key Observations:
* Magnesium metal will react vigorously, producing bubbles of hydrogen gas.
* The solution will become warm due to the heat released during the reaction.
* The solution will change color as magnesium chloride dissolves.
