As compared to lithium,sodium reacts quickly with water because

$A$ metal $M$ reacts with $N_2$ to give a compound '$A$' $(M_3N)$. '$A$' on heating at high temperature gives back '$M$' and '$A$' on reacting with $H_2O$ gives a gas '$B$'. '$B$' turns $CuSO_4$ solution blue on passing through it. $A$ and $B$ can be

The alkali metal with the lowest $E^{\circ}_{M^{+}/M} (V)$ is $X$ and the alkali metal with the highest $E^{\circ}_{M^{+}/M} (V)$ is $Y$. Then $X$ and $Y$ are respectively:

Which of the following will release hydrogen gas upon reaction with hydrochloric acid?

Given below are two statements:
Statement $I$: The chlorides of $Be$ and $Al$ have $Cl^{-}$-bridged structure. Both are soluble in organic solvents and act as Lewis acids.
Statement $II$: Hydroxides of $Be$ and $Al$ dissolve in excess alkali to give beryllate and aluminate ions.
In the light of the above statements,choose the correct answer from the options given below.

Match List-$I$ with List-$II$ :

List-$I$	List-$II$
$(a)$ $Li$	$(i)$ Poor water solubility of $I^{-}$ salt
$(b)$ $Na$	$(ii)$ Most abundant element in cell fluid
$(c)$ $K$	$(iii)$ Bicarbonate salt used in fire extinguisher
$(d)$ $Cs$	$(iv)$ Carbonate salt decomposes easily on heating
