Question

Identify the following reaction as a combination, single displacement, double displacement, combustion, or decomposition reaction:

Mg+ 2HCl= MgCl₂ +H₂

Answer 1

The given reaction Mg + 2HCl → MgCl₂ + H₂ is a single displacement reaction.

Step-by-step explanation:

The given reaction: Mg + 2HCl → MgCl₂ + H₂

This reaction is a single displacement reaction. In a single displacement reaction, one element replaces another element in a compound. In this case, magnesium (Mg) replaces hydrogen (H) in hydrochloric acid (HCl), resulting in magnesium chloride (MgCl₂) and hydrogen gas (H₂) as the products.

Here is the balanced chemical equation for the reaction: Mg + 2HCl → MgCl₂ + H₂
