Answer 2
Answer:

Answer:

a. CFCs

Explanation:

Chlorofluorocarbons or CFCs are known as chemical compounds that are manufactured that have carbon, fluorine and chlorine; When these three reach the stratosphere, they enter into a process of division that forces them to release the chlorine atoms, which completely destroy the ozone layer.  UV radiation strips chlorine from a chlorofluorocarbon (CFC) molecule. This chlorine atom, when combined with an ozone molecule destroys it, but originates another active species (chlorine monoxide) that restarts new stages of destruction.

CFCs are derived from hydrocarbons that saturate and originate after the hydrogen atoms are exchanged for fluorine and chlorine atoms, these being the main elements.

It is necessary to comment that the name "CFC" is known as a generic nickname for the group of compounds formed by fluorine, chlorine and carbon, which are used as cold and gas producing agents in aerosols.

At present, it is known that the appearance of the hole in the ozone layer, exactly over Antarctica, is related to the photochemistry caused by CFCs that are found in different commercial products.

Most countries were ruled by some form of authoritarian governments. This mostly included kings or religious leaders. There was no democracy and no things such as election, but rather the monarch could do as he or as she pleased. This slowly started to change with addition of constitutions and development of republican sentiment around the times of the fall of Bastille and the separation of the US.
