Loss of atmospheric ozone has led to an ozone "hole" over Antarctica. The process occurs in part by three consecutive reactions. (Each of the reactants and products in these reactions are gases.)
(1) Chlorine atoms react with ozone (O3) to form chlorine monoxide and molecular oxygen.
(2) Chlorine monoxide forms ClOOCl.
(3) ClOOCl absorbs sunlight and breaks into chlorine atoms and molecular oxygen. If the coefficient for a particular substance is "1", do not write the "1" in the balanced equation. For example, instead of writing "1Cl(g)", simply write "Cl(g)".
(a) Write a balanced equation for each step, including the state of each molecule.
(b) Write an overall balanced equation for the sequence.

Respuesta :

Ozone O₃ consists of a strong reactive gas made up of three atoms of oxygen. Ozone occurs on the Earth as natural and man-made gas.

Ozone impacts life on Earth in positive or harmful ways depending upon its location in the atmosphere.

From the information given, we are to balance the reactant and the product that leads to the formation of Ozone by following each step.

Step 1:

2Cl° + 2O₃           2ClO°        +        2O₂

                          Chlorine               molecular

                          monooxide            oxygen

Step 2:

2ClO°                  ClOOCl

Step 3:

ClOOCl     + sunlight   →    2Cl°      + O₂

(b)

The Overall balanced equation can be expressed as:

2O₃    →    3O₂

Therefore, from the above explanation we can see the step by step process for the balanced equation and the overall balanced equation.
