Question

How many moles of KCIO3 most decompose to form 13.0 moles of potassium chloride?

Answer 1

13 moles of KClO₃ will decompose to gives 13 moles of KCl.

Step-by-step explanation:

Given data:

Moles of potassium chloride = 13.0 mol

Moles of KClO₃ = ?

Solution:

Chemical equation:

2KClO₃ → 2KCl + 3O₂

Now we will compare the moles of KCl with KClO₃.

KCl : KClO₃

2 : 2

13 : 13

So 13 moles of KClO₃ will decompose to gives 13 moles of KCl.
