The sodium was burned in air. The resulting solid absorbs carbon dioxide to liberate oxygen and liberate salt. The latter salt was dissolved in hydrochloric acid, and a solution of silver nitrate was added to the resulting solution. This resulted in a white curdled precipitate. Write the equations for the described reactions.
2Na + O2 → Na2O2
2Na2O2 + 2CO2 → 2Na2CO3 + O2↑
Na2CO3 + 2HCl → 2NaCl + CO2↑ + H2O
NaCl + AgNO3 → AgCl↓ + NaNO3
