By Ritesh|Updated : November 8th, 2022

The balanced equation is N2 (g) + 3H2 (g) → 2NH3(g). Steps to calculate the Balance of the equation: N2 + H2 → NH3.

Step 1: Given the equation:

N2 + H2 → NH3

Step 2: The procedure used to balance the equation

utilising the standard approach for balancing chemical equations. In line with the method:

  • To start, add up all the atoms of each element on both the reactant and product sides.
  • Molecules containing an element with a distinct number of atoms on the reactant side and the product side should be given stoichiometric coefficients.
  • The number of atoms on either side must be balanced by the coefficient.
  • Typically, the hydrogen and oxygen stoichiometric coefficients are assigned last.
  • The stoichiometric coefficient must be multiplied by the total number of atoms of an element present in 1 molecule of the species to determine the number of atoms in one species.
  • Continue doing this until both the reactant and product sides have the same number of all the atoms of the reacting components.

Step 3: Balancing the given chemical equation

The given equation is:

N2 + H2→ NH3

Reactant side:

  • 2 Nitrogen atoms
  • 2 Hydrogen atoms

Product side:

  • 1 Nitrogen atom
  • 3 Hydrogen atoms

The nitrogen atoms are balanced initially. After being balanced, the equation is: N2 + 3H2 → 2NH3

The hydrogen atoms are finally balanced. After being balanced, the equation is: N2 + 3H2→ 2NH3

Reactant side:

  • 2 Nitrogen atoms
  • 6 Hydrogen atoms

Product side:

  • 2 Nitrogen atom
  • 6 Hydrogen atoms

The equation is balanced because there are an equal number of all the atoms of the reacting components on both the reactant and product sides.

Hence the balanced equation is: N2 (g) + 3H2 (g) → 2NH3(g)

Summary:

Balance the equation: N2 + H2 → NH3

The balanced chemical equation of N2 + H2 → NH3 is N2 (g) + 3H2 (g) → 2NH3(g). It can be done by making the atoms on both the reactant and product sides equal based on the law of conservation of mass.
