The order of negative standard electrode potential values $(E^\circ_{M^+/M})$ for $Li$,$Na$,and $K$ is:

$KO_2 + CO_2 + H_2O \xrightarrow{\text{more } CO_2} [X] + [Y]$
Products $[X]$ and $[Y]$ are respectively

By using which process, sodium carbonate is generally prepared?

The solubility of the alkali metal carbonates:

$A$ $s$-block element $(M)$ reacts with oxygen to form an oxide of the formula $MO_{2}$. The oxide is pale yellow in colour and paramagnetic. The element $(M)$ is:
