Fe + HCl = FeCl2 + H2

Balanced Chemical Equation – Solution

Fe + 2HCl → FeCl2 + H2

The coefficients show the number of particles (atoms or molecules), and the indices show the number of atoms that make up the molecule. New substances are formed as a result of the rearrangement of the original atoms. As a result of a chemical reaction, atoms of chemical elements do not disappear anywhere and new ones do not appear, their number remains unchanged – this follows from the law of conservation of mass of substances.

Chemical Reaction Information

Iron + Hydrogen Chloride = Ferrous Chloride + Tritium

This is an oxidation-reduction (redox) reaction. HCl is an oxidizing agent, Fe is a reducing agent.

  • 2 HI + 2 e  2 H0 (reduction)
  • Fe0  2 e  FeII (oxidation)
