Question

3

Using the balanced equation
2 KCIO3 2 KCl + 302
If 9.6 moles of O2 are produced, how many moles of KCIO3 are decomposed?
6

Answer 1

6.4 moles of KClO₃ are decomposed

Step-by-step explanation:

Given data:

Number of moles of O₂ produced = 9.6 mol

Number of moles of KClO₃ decomposed = ?

Solution:

Chemical equation:

2KClO₃ → 2KCl + 3O₂

now we will compare the moles of oxygen and KClO₃.

O₂ : KClO₃

3 : 2

9.6 : 2/3×9.6 = 6.4 mol

Thus, 6.4 moles of KClO₃ are decomposed.
