Question

1)Ozone first decomposes to give molecular Oxygen and nascent Oxygen. 2)Nascent oxygen then oxidises lead(11)sulphide to give lead(11)sulphate

Answer 1

Answer:

here's the answer please mark as the brainliest .

Explanation:

This is a semi-standard example of why 'naive' balancing does not work.

Ozone is a source of atomic oxygen, producing free oxygen molecules. So, in 'mild' conditions only one oxygen per ozone molecule would react as a strong oxidizer, and the remaining molecular oxygen would require elevated temperatures to react. Thus the equation would be

PbS+4O3⟶PbSO4+4O2

Similarly, in excess of reducer at elevated temperature (though why would you want it with ozone is another matter) all atoms in ozone would react. Thus, the reaction should be

3PbS+4O3⟶3PbSO4
