Sodium is heated in air at $${300^ \circ }C$$ to form $$X.$$ $$X$$ absorbs $$C{O_2}$$ and forms $$N{a_2}C{O_3}$$ and $$Y.$$ Which of the following is $$Y?$$
A.
$${H_2}$$
B.
$${O_2}$$
C.
$${H_2}{O_2}$$
D.
$${O_3}$$
Answer :
$${O_2}$$
Solution :
\[2Na+{{O}_{2}}\xrightarrow{{{300}^{\circ }}C}\underset{\left( X \right)}{\mathop{N{{a}_{2}}{{O}_{2}}}}\,\]
$$\mathop {2N{a_2}{O_2}}\limits_{\left( X \right)} + 2C{O_2} \to 2N{a_2}C{O_3} + \mathop {{O_2}}\limits_{\left( Y \right)} $$
