N2 + H2 = NH3

Balanced Chemical Equation – Solution

N2 + 3H2 → 2NH3

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

Dinitrogen + Tritium = Ammonia

This is an oxidation-reduction (redox) reaction. H2 is a reducing agent, N2 is an oxidizing agent.

  • 6 H0  6 e  6 HI (oxidation)
  • 2 N0 + 6 e  2 N-III (reduction)

Reaction Type


Substances that react are called starting materials or reactants. The substances that form as a result are called reaction products.
