Question

what is formed when sodium absorbs moisture from air? give equation also ​

Answer 1

Answer:

When the sodium metal react with atmospheric oxygen to give sodium peroxide as a product. By the stoichiometry we can say that 2 moles of sodium metal react with 1 mole of oxygen to give 1 mole of sodium peroxide as a product. Hence, the sodium peroxide is formed when sodium absorbs moisture from air..

Explanation:

When sodium is exposed to moist air it forms a coatin of NaO2 and prevents the further reaction of the metal with air. With water it gives NaOH and H2.
