    2NH₂ + O₂ → N₂ + 2H₂O

    Explanation:

    Balancing the equation means, the number of atoms on both sides of the equation must be the same.

    In the case of the given equation, we have to find out whether it is balanced or not.

    2NH₂ + O₂ → N₂ + 2H₂O

    Atoms Number of atoms before balancing after balancing

    LHS RHS LHS RHS

    N 1 2 2 2

    H 2 2 4 4

    O 2 1 2 2

    To balance the N atoms, we have to put 2 in front of NH₂, and then to balance the H, O atoms, we have to put 2 in front of H₂O, so that each atom in left hand as well as right hand side of the equation was balanced.
