Q:

What does hydrochloric acid and magnesium make?

A:

Quick Answer

The chemical reaction between magnesium and hydrochloric acid produces magnesium chloride and hydrogen. The balanced chemical equation for this reaction is 2HCL(aq) + Mg(s) produces MgCl2(aq) +H2(g), where the subscripts refer to the substance's form, such as aq stands for aqueous, g is a gas, and s is a solid.

Full Answer

Magnesium is a metal that reacts with an acid to from the salt magnesium chloride and hydrogen gas. A salt and hydrogen gas are the products of any reaction that involves a metal and an acid. The chemical equation can be written as a metal + acid produces a salt + hydrogen.

The reaction between magnesium and hydrochloric acid is also known as a single replacement reaction. In this type of chemical reaction, an element from a compound is displaced by another element. A single replacement reaction is also referred to as a single displacement reaction. This type of chemical reaction often involves either hydrochloric or sulfuric acid, which are strong acids.

Single replacement reactions can be represented by the simple chemical equation FY + C produces F + CY. For this kind of reaction to occur, an element that is more reactive has to displace one with less reactivity. Similarly, a displacement reaction takes place when a solid reactant is placed in a solution. Single replacement reaction also are not reversible reactions.
