When burning in air, the unknown metal forms two products: the main one, the molecule of which contains 38 e¯, and the side one, the molecule of which contains 30 e¯. The main product of the combustion reaction is used to produce oxygen in submarines. Determine which metal you are talking about.
When Na burns in air, the main product Na2O2 is formed.
The number e = 2 * 11 + 2 * 8 = 38.
Na2O by-product.
The number e = 2 * 11 + 8 = 30.
Na2O2 is used for oxygen production, absorption of carbon monoxide and carbon dioxide in regeneration plants:
2 CO2 + 2 Na2O2 → 2 Na2CO3 + O2.
Answer: Na.
