Question

Put in word equation chlorine + potassium nitride -> nitrogen + potassium chloride

Answer 1

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.
