Question
Write one chemical reaction for the preparation of $\mathrm{D}_2 \mathrm{O}_2$.
✓
Answer
$\mathrm{D}_2 \mathrm{O}_2$ can be prepared by the reaction of $\mathrm{D}_2 \mathrm{SO}_4$ dissolved in water over $\mathrm{BaO}_2$.
$\mathrm{BaO}_2+\mathrm{D}_2 \mathrm{SO}_4 \rightarrow \mathrm{BaSO}_4+\mathrm{D}_2 \mathrm{O}_2$
$\mathrm{BaO}_2+\mathrm{D}_2 \mathrm{SO}_4 \rightarrow \mathrm{BaSO}_4+\mathrm{D}_2 \mathrm{O}_2$
