Question

describe an experiment for the preparation and collection of oxygen from sodium peroxide

Answer 1

It can react with carbon dioxide in the presence of water:

sodium peroxide + carbon dioxide + water → sodium bicarbonate + oxygen

2 Na2O2             + 4 CO2           + 2 H2O   → 4 NaHCO3             + O2

(This assumes a huge excess of carbon dioxide; sodium carbonate or sodium hydroxide are alternative products that might form if less carbon dioxide were available, or other acids might get into the action if present.)

Answer 2

Answer:it reacts with carbon dioxide in the presence of water

Explanation:this is because

Carbon dioxide is more reactive
