calculations for mole ratio on KCLO3, KCL, and O2 and explanation on how to do it so I can better understand. please and thank you.
I thought you can only do mole ration if you have an equation and after you balance. I'm so confused.

Answer 1

kindly rate the answer.

Moles calculated by you are correct for each compound. for calculation of molar ratio ; moles of compound whose molar satio to I becalculated moles of least compound Molar ratio for KClO₂ = 0.01615 mol 0.01604 mol molar ratio for kle = 0.01604 mol 0.01604 mol = molar ratio for q = 0.0245 mol 0.01604 mol - 1.5 setts your answet is completed above, (0.01604 moles were least). further info. o Multiply this obtained molar ratio's by 2 , to get whole number ratio of compounds i.e. KClO₂ = 2, Ke=2 and Og = 3 This is in agreement with the balanced dissociation equation of KClO3 on heating ; 2 KClO3(s) A 2 kce (s) + 3 02 (9) n
