Write a balanced equation for the overall reaction:

Step 1 O3 + Cl --> O2 + ClO
Step 2 ClO + O --> Cl + O2

=

O3 + O --> 2O2

Is that correct?
or would it be

O3 + O --> O2 + O2

To determine the balanced equation for the overall reaction, we need to combine Step 1 and Step 2. Let's analyze the elements and their respective quantities on both sides of each step.

Step 1:
1 O3 molecule reacts with 1 Cl atom, producing 1 O2 molecule and 1 ClO molecule.

Step 2:
1 ClO molecule reacts with 1 O atom, producing 1 Cl atom and 1 O2 molecule.

To ensure the conservation of atoms in the overall reaction, we need to make the number of atoms of each element the same on both sides of the equation.

Here is the balanced equation for the overall reaction:

2 O3 + 2 O → 2 O2 + 2 O2

In this balanced equation, 2 molecules of O3 react with 2 atoms of O, producing 2 molecules of O2 and 2 molecules of O2.

Therefore, the correct balanced equation for the overall reaction is:

2 O3 + 2 O → 2 O2 + 2 O2
