    Since the question is incomplete, see below an explanation.

    Explanation:

    From the word equation, you can write the molecular equation, and the balanced molecular equation, which is a basic skill that chemistry studends must develop.

    1. Write the chemical formula of each reactant and product

    a) Chlorine: Cl₂ (g). It is a diatomic gas at room temperature and standard pressue.

    b) Potassium nitride is a salt formed by N₃⁻ ion and K⁺ ion. It is a solid at room temperature.

    KN₃

    c) Nitrogen: N₂ (g). It is a diatomic gas at room temperature and standard pressure

    d) Potassium chloride: it is the salt with the ions K⁺ and Cl⁻. It is also a solid at room temperature.

    KCl

    2. Write the molecular chemical equation:

    Cl₂ (g) + KN₃ → N₂ (g) + KCl

    3. Balance the molecular equation:

    Add the needed coefficients to balance both sides of the equation:

    Cl₂ (g) + 2KN₃ → 3N₂ (g) + 2KCl

    Count the number of each kind of atom on each side:

    Cl: two atoms on each side K: two atoms on each side N: sixe atoms on each side

    Then, the equation is balanced.
