The ozone "hole" over Antarctica formed as the result of a series of chemical reactions. The loss occurs in part through three consecutive steps in which ozone is broken down: Step 1: Chlorine atoms react with ozone (O3) to form chlorine monoxide and molecular oxygen. Step 2: Chlorine monoxide molecules combine to form ClOOCl gas Step 3: ClOOCl absorbs sunlight and breaks into chlorine atoms and molecular oxygen. a) Write a balanced equation for each step. b) Write an overall balanced equation for the sequence
