Question

In two or more complete sentences explain how to balance the chemical equation, KClO3 ⟶ KCl + O2 and include all steps. Write your response in the essay box below.

Answer 1

Answer:

Your first step is to balance the oxygen in the equation. It is often best to start with whichever element you have the most of.

You balance the oxygen by multiplying O2 by 3 and KClO3 by 2.

1) 2KClO3 --> KCl + 3O2

Next you must now balance the Potassium and Chlorine atoms. To do this, simply multiply the KCl by 2.

2) 2KClO3 --> 2KCl + 3O2

Now you have 2 Potassium, 2 Chlorine and 6 Oxygen on each side of the equation.

Explanation:

Answer 2

The balanced chemical reaction is -

2kClO₃ ---------> 2KCl + 3O₂

The steps to balance the given chemical equation are as follows-

1. In the first step, we need to balance the oxygen atoms both on the reactant side and product side. We will multiply O₂ by 3 and KClO₃ by 2.

The reaction is as follows-

2KClO₃ -----------> KCl + 3O₂

• Number of oxygen atoms in reactant and product side = 6
• Number of Atoms of Potassium on reactant side = 2
• Number of Atoms of Potassium on product side = 1
• Number of the chlorine atom on the reactant side = 2
• Number of the chlorine atom on the product side = 1

2. In the next step, to balance the number of atoms of potassium and chlorine, we will multiply kCl by 2

2kClO₃ ---------.> 2KCl + 3O₂

Now we have 2 atoms of potassium, 2 atoms of chlorine, and 6 atoms of Oxygen on both sides of the reaction.
