The answer would be c. Have you ever seen gravy? It always separates and leaves different layers.
There are 2 valence elcetrons
Answer:
Explanation:
given reaction
2O₃ ⇄ 3O₂
initial 1 1
final 1-x 1+ 1.5x
rate of reaction = k [ O₃ ]² / [ O₂ ]
initial rate = k . 1² / 1 = k
final rate = k (1-x )² / (1+ 1.5x) = k/2
(1-x )² / (1+ 1.5x) = 1/2
2x² - 5.5 x + 1 = 0
x = 0.196
So fraction of ozone reacted = .196
