Potassium perchlorate, KCIO4, is a betteroidizing agent than the potassium chlor

Question

Potassium perchlorate, KCIO4, is a betteroidizing agent than the potassium chlorate, KCO3, described in the previous problem. Potassium perchlorate, which is used in explosives, fireworks, flares, and solid rocket propellants, is made by carefully heating potassium chlorate to between 400°C and 500°C. The unbalanced equation for this reaction is (a) Balance this equation. (Use the lowest possible whole number coefficients. Omit states-of-matter in your answer.) chemPad Help Greek (b) Write a conversion factor that could be used to convert between moles of potassium chlorate and moles of potassium perchlorate. (Use the lowest possible whole number factors.) mol KCIO4 mol KCIO3 (c) How many moles of potassium perchlorate form from the complete reaction of 83 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. mol KCI mol KCIO4 (e) How many moles of potassium chloride form along with 14.256 moles of potassium perchlorate? 40 mol

Explanation / Answer

a) balanced equation:  

     4KClO3 ---> 3KClO4 + KCl

4 mol KClO3 = 3 mol KClO4 = 1 mol KCl

b) conversion factor = 3 mol KClO4 /4 mol KClO3

c) no of mol of KClO4 formed = 83*3/4 = 62.25 mol

d) conversion factor = 1 mol KCl / 3 mol KClO4

e) no of mol of KCl formed = 14.256*1/3 = 4.752 mol
