- D \(2 \mathrm{KI}_{(\mathrm{aq})}+\mathrm{H}_2 \mathrm{O}_{(\mathrm{l})}+\mathrm{O}_{3(\mathrm{~g})} \rightarrow2 \mathrm{KOH}_{(\mathrm{aq})}+\) \(\mathrm{I}_{2(\mathrm{~g})}+\mathrm{O}_{2(\mathrm{~g})}\)
Answer & Solution
Correct Answer
(B) \(\mathrm{BaO}_{2(\mathrm{~g})}+\mathrm{O}_{3(\mathrm{~g})} \rightarrow \mathrm{BaO}_{(\mathrm{s})}+2 \mathrm{O}_{2(\mathrm{~g})}\)
Step-by-step Solution
Detailed explanation
Ozone is a reducing agent:
Ozone converts peroxides to oxides and is converted to oxygen in exchange.
Barium peroxide is reduced to barium oxide by ozone.
\(\mathrm{BaO}_2+\mathrm{O}_3 \rightarrow \mathrm{BaO}+2 \mathrm{O}_2\)
Ozone converts peroxides to oxides and is converted to oxygen in exchange.
Barium peroxide is reduced to barium oxide by ozone.
\(\mathrm{BaO}_2+\mathrm{O}_3 \rightarrow \mathrm{BaO}+2 \mathrm{O}_2\)
