Which of the following is the primary cause of stratospheric ozone depletion? Chlorine atoms in CFCs

Answer A: Chlorine atoms in C F Cs
A

Sulfur dioxide in photochemical smog

Answer B: Sulfur dioxide in photochemical smog
B

Mercury released from the combustion of coal

Answer C: Mercury released from the combustion of coal
C

PANS from automobile exhaust

(The answer is A)

A

Explanation:

A

Explanation: Ozone depletion occurs when chlorofluorocarbons (CFCs) and halons—gases formerly found in aerosol spray cans and refrigerants—are released into the atmosphere (see details below). ... CFCs and halons cause chemical reactions that break down ozone molecules, reducing ozone's ultraviolet radiation-absorbing capacity.

ek = (m·v2) / 2

v - velocity of system after the collision

m = m1 + m2

ek = (m1 + m2) ·v2/2

ek = (200 + 250) ·2,32/2 = 450·5,29/2 = 1190,25 j

answerthe above statement is (true);
