a. 2KClO3 (s) -> 2KClO2 (s) + O2 (g) b. KClO3 (s) -> KClO (s) + O2 (g) c. 2KClO3

Question

a. 2KClO3 (s) -> 2KClO2 (s) + O2 (g)

b. KClO3 (s) -> KClO (s) + O2 (g)

c. 2KClO3 (s) -> 2KCl (s) + 3O2(g)

In the appropriate spaces above, fill in the values of the ratio (moles O2 / moles KClO3) based on the stoichiometric coefficients of the three balanced equations.

PS: I want to know No.3 question, not No.2. Thanks!

2. Following are three possible reactions that could occur when a sample of KCIOs (s) is heated. One goal of this lab is to determine the correct one. Balance all three reactions. b.-. KCIOs (s) -KCIO (s) +--02 (g) 3. In the appropriate spaces above, fill in the values of the ratio (moles O2/ moles KCIOs) based on the stoichiometric coefficients of the three balanced equations

Explanation / Answer

3. They want you fill the last space by ration (moles of O2/moles of KCLO3)

for a : It will be 1/2

for b : It will be 1/1 =1

for c : It will be 3/2
