Answer:
- 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.
