Question

Which is a decomposition reaction and which is not?

a) 3 O2 → 2 O3

b) 2 KClO3 → 2 KCl + 3 O2​

Answer 1

Answer:

HERE IS YOUR ANSWER

Explanation:

OPTION B IS A DECOMPOSITION REACTION BECAUSE A COMPOUND BREAKS TO GIVE TWO DIFFERENT COMPOUNDS

NOW OPTION A IS NOT DECOMPOSITION

BECAUSE THE ACTUAL REACTION OF OXYGEN TO BECOME OZONE IS CARRIED OUT BY OXYGEN REACTING WITH NASCENT OXYGEN REPRESENTED BY [0]

Nascent oxygen is the oxygen which hasn't bonded covalently with another oxygen atom to form O2

SO DECOMPOSITION-B
