Question

If $Na$ is heated in presence of air, it forms

• A. $N{a}_{2}C{O}_3$
• B. $N{a}_2{O}_2$
• C. $N{a}_{2}O$
• D. Both $\left(B\right)$ and $\left(C\right)$

Answer 1

The correct option is D Both $\left(B\right)$ and $\left(C\right)$

When Na is heated in the presence of air or oxygen, Na burns to form sodium oxide and sodium peroxide.

$6Na+2O_2\to 2N{a}_{2}O+N{a}_2{O}_2$
