Potassium perchlorate, KClO 4 , is a better oxidizing gent than potassium chlora

Question

Potassium perchlorate, KClO4, is a better oxidizing gent than potassium chlorate, KClO3. Potassium perchlorate, which is used in explosives, fireworks, flares and solid rocket propellants, is made carefully by heating potassium chlorate to between 400*C and 500*C. The unbalanced equation for this reaction is : KClO3 -> KClO4 + KCl

A) Balance this equation

B) Write a conversion factor that could be used to convert between moles of potassium chlorate and moles of potassium perchlorte.

C) How many moles of potassium perchlorate form from the complete reaction of 12 moles of potassium chlorate?

D) Write a conversion factor that could be used to convert between moles of potassium perchlorate and moles of potassium chloride.

E) How many moles of potassium chloride form along with 11.875 moles of potassium perchlorate?

Explanation / Answer

a) 4 KClO3 ---> 3 KClO4 + KCl is the required balanced equation.

b) 1 Mole of potassium perchlorate = 4.3 moles of Potassium chlorate. So, for every one mole of Potassium chlorate taken, we get 3/4 mole of potassium perchlorate.

c) Ans = 3/4 * 16 = 12 moles of Potassium perchlorate

d) 3 moles of potassium perchlorate has 1 mole KCl. So, per 1 mole of KCl, conversion factor is 3.

e) Ans = 11.875/3 = 3.96 moles of KCl
