When air descends it compresses. When the air compresses the molecules in the air knock into each other more often, increasing the tempertature.
Hope this helps
Chlorine is a halogen and is very reactive and unstable. If released in an elemental form (Cl2), it would react with other substances immediately. However, <span>chlorofluorocarbons (CFCs) which contain chlorine are unreactive and when released they eventually end up in the upper atmosphere still "intact". In the upper atmosphere, sunlight is more intense and is able to break apart CFC, releasing the highly reactive chlorine which in turns destroys ozone which is more abundant in the upper atmosphere (stratosphere). </span>
Silicone is most similar to carbon.
hope this helps; and good luck.
Single displacement and combustion reactions are ALWAYS redox.
