Answer to Question #52436 in Inorganic Chemistry for kayla

Question

How many moles of O2 can be produced by letting 6.0 moles of KClO3 react based on the below equation?

2KClO sub 3, reaction arrow, 2KCl + 3O sub 2.

Answer 1

The equation is:
2KCIO₃ = 3KCI + 3O₂
The molar ratio of KClO₃ to O2 in this reaction is 2/3
Using this ratio we can find the number of moles of O₂: 2/3=6/x; x=(3 x 6)/2 = 9 moles
