Can someone explain how to do this?

Balanced equation :

3H₂+N₂⇒2NH₃

Equalization of chemical reaction equations can be done using variables. Steps in equalizing the reaction equation:

1. gives a coefficient on substances involved in the equation of reaction such as a, b, or c etc.

2. make an equation based on the similarity of the number of atoms where the number of atoms = coefficient × index between reactant and product

3. Select the coefficient of the substance with the most complex chemical formula equal to 1

Unbalanced⇒the number of atoms from both sides (reactants and products) is not the same

H₂+N₂⇒NH₃

H=2(left), H=3(right)

N=2(left), N=1(right)

Balanced ⇒ the number of atoms from both sides (reactants and products) is equal

3H₂+N₂⇒2NH₃

H=3x2=6(left), H=2x3=6(right)

N=2(left), N=2x1=2(right)
