What else is produced during the replacement reaction of magnesium and hydrochloric acid? mg 2hcl h2 ________ mgcl2 mg2cl2 mg2cl mgcl

Respuesta :

During the replacement reaction of magnesium and hydrochloric acid MgCl₂ is produced with hydrogen gas.

What is replacement reaction?

Replacement reactions are those reactions in which one entity from the one of the reactant will replace by another entity for the formation of the product.

Balanced chemical reaction between magnesium and HCl will be represented as:

Mg²⁺  +  2HCl  →  MgCl₂  +  H₂

In the baove reaction magnesium displaces hydrogen atom from the acid molecule.

  • Formation of Mg₂Cl₂ is impossible because valency of magnesium is not satisfied in this.
  • Formation of Mg₂Cl is also impossible because valency of magnesium is not satisfied in this.
  • Formation of MgCl is also impossible because valency of magnesium is not satisfied in this, as valency of Mg is +2 and of Cl is -1.

Hence MgCl₂ is produced in the reaction.
