What is the main concern with CFC decomposition?

1. It creates hazardous waste

2. It releases greenhouse gases

3. It produces harmful acids

4. It reduces energy efficiency

The correct answer is: It produces harmful acids

The main concern with CFC (chlorofluorocarbon) decomposition primarily revolves around the production of harmful acids. When CFCs decompose, particularly in the stratosphere, they release chlorine atoms. These chlorine atoms can react with ozone (O3) molecules, leading to the depletion of the ozone layer. This depletion is of great concern because the ozone layer plays a critical role in protecting life on Earth from the sun’s harmful ultraviolet (UV) radiation. The production of harmful acids is particularly significant because it can lead to increased acidity in the atmosphere, contributing to problems such as acid rain, which can have devastating effects on ecosystems, waterways, and human-made structures. Understanding this interaction highlights the environmental impact of CFCs and their derivatives, making it imperative to manage and phase out the use of substances that lead to the creation of these harmful byproducts.
