Answer 3

I will answer in detail. Mark the correct statements:

1. Ozone completely surrounds the Earth's atmosphere at an altitude of 25 km 2. Ozone protects the planet from harmful infrared radiation 3. Ozone is used for ozonation of air and drinking water, purifying them 4. The main cause of ozone layer depletion is freon gases 5. Aviation and space flights do not affect the destruction of the ozone layer

The correct statements are 3 and 4. Let me explain why:

- Statement 1 is false because ozone is not evenly distributed in the atmosphere. It is concentrated in a layer called the ozone layer, which is located between 15 and 35 km above the Earth's surface. - Statement 2 is false because ozone does not block infrared radiation, which is emitted by the Earth and warms the atmosphere. Ozone absorbs ultraviolet (UV) radiation, which is harmful to living organisms and can cause skin cancer and eye damage. - Statement 3 is true because ozone is a powerful oxidant that can kill bacteria, viruses, fungi, and other microorganisms. Ozone is used for disinfection of air and water, as well as for deodorization and bleaching. - Statement 4 is true because freon gases, also known as chlorofluorocarbons (CFCs), are synthetic chemicals that are used in refrigeration, air conditioning, aerosol sprays, and foam production. CFCs can reach the stratosphere, where they are broken down by UV radiation and release chlorine atoms, which destroy ozone molecules. - Statement 5 is false because aviation and space flights can also contribute to ozone depletion. Jet engines emit nitrogen oxides, which react with ozone and reduce its concentration. Rocket launches release water vapor, chlorine, and aluminum oxide, which can also damage the ozone layer .
