Loss of atmospheric ozone has led to an ozone “hole” overAntarctica. The process occurs in part by three consecutive reac-tions: (1) Chlorine atoms react with ozone (O₃) to form chlorinemonoxide and molecular oxygen. (2) Chlorine monoxide forms ClOOCl. (3) ClOOCl absorbs sunlight and breaks into chlorine atoms andmolecular oxygen.(a) Write a balanced equation for each step.(b) Write an overall balanced equation for the sequence.

Stoichiometry

Stoichiometry is a chemical division that evaluates the quantitative content of the chemical process with the help of the reacting molecules or products taking part in the reaction. The term “stoicheion” in “Stoichiometry”, is an old Greek term for "element" whereas “metron” means "measure".
