The reaction described is a classic example of a single displacement reaction, where a metal displaces hydrogen in an acid to form a salt and release hydrogen gas.
This reaction is a single displacement reaction, also known as a displacement reaction or a replacement reaction. In this type of reaction, one element replaces another in a compound.
Metals react with hydrochloric acid to produce the metal chloride and hydrogen gas. The following is an example of the reaction between magnesium metal and hydrochloric acid. Mg(s) + 2HCl(aq) --> MgCl2(aq) + H2(g)
A reactive non-metal.
Hydrogen gas is liberated when metals react with acid. The explanation lies in the fact that the the presence of hydrogen in a substance makes it acidic. so, every acid will contain Hydrogen. When metals reach with an acid, they form their respective salts according to the acid and always liberate hydrogen from that acid. If the acid is H2SO4, then the salt will sulfate of whichever metal reacts with the acid. If the acid is HCl, then the product would be metal chloride.
A metal that is more reactive than hydrogen, such as zinc or magnesium, will react with an acid to form hydrogen gas. The metal will displace the hydrogen ions in the acid, resulting in the production of hydrogen gas.
The reaction represents a single replacement reaction where the metal displaces the hydrogen in the acid to form a salt and releases hydrogen gas as a byproduct.
This is usually called a "displacement" reaction; a metal higher in the electromotive series is displacing a metal below it in the electromotive series in a compound of the latter.
The reaction represented is a double displacement reaction, where the metal oxide and nonmetal oxide react to form a ternary salt. In this reaction, the metal from the metal oxide replaces the cation in the nonmetal oxide to form the salt.
Corrosion is the type of reaction between metals and acids.
When a metal reacts with an acid, the products are a salt and hydrogen gas. The metal displaces the hydrogen in the acid (usually dilute hydrochloric acid or sulfuric acid), forming a salt of the metal and releasing hydrogen gas as a byproduct.
