Hi yall! Does anyone know how one can solve kinetíc energy of H-atom if the dissociation energy and the wavelenght of photons are known when HBr-molecules are photodissociated? Tricky... 
The Earth's atmosphere is primarily made up of nitrogen (78%) and oxygen (21%). The remaining 1% is made up of trace gases such as carbon dioxide, water vapor, and argon.
The greenhouse effect is a natural process that helps regulate the Earth's temperature by trapping heat from the sun. However, human activities such as burning fossil fuels have increased the amount of greenhouse gases in the atmosphere, leading to an enhanced greenhouse effect and causing global warming.
The ozone layer is a layer of gas in the Earth's stratosphere that helps protect us from the sun's harmful ultraviolet radiation. Without the ozone layer, life on Earth would not be able to thrive as UV radiation can cause damage to living organisms.
Air pollution, specifically from human activities, can introduce harmful chemicals and pollutants into the atmosphere. These pollutants can react with other chemicals in the atmosphere to form smog and acid rain, which can have negative impacts on both human health and the environment.
One major issue is the depletion of the ozone layer due to the release of ozone-depleting chemicals such as chlorofluorocarbons (CFCs). Another issue is the increasing levels of greenhouse gases in the atmosphere, leading to climate change and global warming. Both of these issues require immediate action to mitigate their impacts on the Earth's atmosphere.
