Question

Review the equation below.

2KCIO3 > 2KCI + 3O2

How many moles of oxygen are produced when 2 mol of potassium chlorate (KCIO3) decompose?

A. 1

B. 2

C. 3

D. 6

The correct answer is C on edge 2021

Answer 1

C) 3

Step-by-step 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.
