ODP - Ozone Depletion Prevention Certification — Questions and Answers

Question 1: What is the chemical formula for Halon 1301?

CBrClF2
CBrF3 (Correct answer)
C2Br2F4
CF3Br2

Correct answer: CBrF3

Halon 1301 is bromotrifluoromethane (CBrF3), consisting of one carbon, one bromine, and three fluorine atoms.

Question 2: The following form(s) of oxygen is (are) involved in the ozone-oxygen cycle.

Triatomic oxygen (O3) (Correct answer)
Atomic oxygen (O)
Diatomic oxygen (O2)
None of the above.

Correct answer: Triatomic oxygen (O3)

Explanation: <br> The ozone-oxygen cycle involves the participation of triatomic oxygen (O3). This cycle is a series of chemical reactions that occur in the Earth's atmosphere and is responsible for the formation and depletion of ozone. In this cycle, ultraviolet radiation breaks down ozone into diatomic oxygen (O2) and atomic oxygen (O), which then reacts with other molecules to form ozone again. Therefore, triatomic oxygen (O3) plays a crucial role in maintaining the balance of ozone in the atmosphere.
