Question

: Bromine is more effective at destroying ozone than are CFCs. Is this statement:

A) True
B) False

Answer 1

False, Bromine is not more effective at destroying ozone than CFCs. Chlorine atoms from CFCs are much more efficient at destroying ozone than bromine atoms.

Step-by-step explanation:

False, Bromine is not more effective at destroying ozone than CFCs. Although both bromine (Br) and chlorine (Cl) atoms can contribute to ozone depletion, studies have shown that chlorine atoms from CFCs are much more efficient at destroying ozone than bromine atoms.

Chlorofluorocarbons (CFCs) are stable compounds that can last in the atmosphere for many years, allowing them to continue depleting ozone over time. On the other hand, bromine atoms are less abundant and have a shorter lifespan in the atmosphere, making them less efficient in ozone destruction.

It is important to note that the use of CFCs has been phased out due to their harmful effects on the ozone layer, and alternative substances are being used.
