Question

Potassium chlorate (KClO3) will decompose to potassium chloride (KCl) and oxygen (O2) in the reaction shown:

2KClO3(s) → 2KCl(s) + 3O2(g)

A chemist allows 20.0 grams of KClO3 to decompose and captures 6.7 grams of O2 as a
result.

Answer 1

Step-by-step explanation:

Theoretical yield is 7.9 g O2

% yield is actual/theoreticalx 100 = 6.7/7.9 X 100= 84.81 % O2
