Question

Review the equation below.

Answer 1

Answer:

C) 3

Explanation:

Given data;

Number of moles of oxygen produced = ?

Moles of KClO₃ decomposed = 2 mol

Solution:

Chemical equation;

2KClO₃      →      2KCl + 3O₂

Now we will compare the moles of KClO₃  with  O₂

                        KClO₃           :           O₂

                           2                :            3

Thus, 3 moles of oxygen are produced.
