Question

$ \begin{array}{ll}\text { List-I } & \text { List-II } \ \text { (A) } O_{3}+C_{2} N_{2} & \text { (1) Black colour } \ \text { (B) } H_{2} O_{2}+O_{3} & \text { (2) Rocket fuel } \ \text { (C) } A g+O_{3} & \text { (3) Tailing } \ \text { (D) } O_{3}+H g & \text { (4) } O_{2}+H_{2} O\end{array} $ The correct match is:

Accepted Answer

A-2, B-4, C-1, D-3. Ozone reacts with cyanogen to form carbonyl products used in rocket propellants, while ozone plus hydrogen peroxide decomposes to oxygen and water. Silver with ozone gives black silver oxide, and mercury with ozone forms a tailing/oxidized deposit.
