CCCTC HVAC: EPA SECTION 608 9TH EDITION
CORE (2019/2020) EXAM QUESTIONS AND
ANSWERS
1. The molecule found in CFCs and HCFCs that depletes ozone is:
A. Fluorine
B. Hydrogen
C. Carbon
D. Chlorine Answer -Correct answer is D. Chlorine
Chlorine is the element that depletes the ozone by attaching itself to one atom of
oxygen from an ozone molecule. The oxygen molecule becomes O2 and chlorine
monoxide. (Page 8 ESCO EPA 9th Edition prep manual)
2. Crop loss, eye disease, and skin cancer have been attributed to
A. Depletion of Stratospheric nitrogen
B. Depletion of Stratospheric chlorine monoxide
C. Depletion of Stratospheric ozone
D. Depletion of Stratospheric oxygen Answer -Correct answer is C. Depletion of
Stratospheric Ozone
Depletion of stratosphere ozone will cause crop loss, increase eye diseases, skin
cancer, reduce marine life, and deforestation. . (Page 8 ESCO EPA 9th Edition prep
manual)

A. 100
B. 1,000
C. 10,000
D. 100,000 Answer -Correct answer is D 100,000
One atom of chlorine will destroy 100,000 molecules of ozone.
