I don’t really understand the question but i’m assuming that’s there’s a chemical reaction happening when the bicyclist is eating the food to get energy to bike?
Halons and cfc’s both destroy ozone layer in the stratosphere.
- Chemicals with carbon, chlorine, and fluorine atoms are known as chlorofluorocarbons (CFCs), and they are neither poisonous nor combustible.
- They are employed as solvents, refrigerants, blowing agents for foams and packaging materials, and in the production of aerosol sprays.
- Halons, hydrochlorofluorocarbons, and chlorofluorocarbons all damage the ozone layer, which protects the planet from damaging ultraviolet (UV-B) rays from the sun.
- Additionally warming the earth's lower atmosphere, CFCs and HCFCs alter the climate on a global scale.
- Life on earth is made possible by the stratospheric ozone layer, which protects the planet from the sun's harmful ultraviolet (UV-B) rays.
- Ozone in the upper atmosphere is destroyed by man-made substances such halons, hydrofluorocarbons, and chlorofluorocarbons (CFCs)
