Hydrogen accepts an electron to form inert gas configuration. In this it resembles

\mathrm{CaC}_2+\mathrm{H}_2 \mathrm{O} \longrightarrow \mathrm{Ca}(\mathrm{OH})_2+' \mathrm{X}\,'

\mathrm{Mg}_2 \mathrm{C}_3+\mathrm{H}_2 \mathrm{O} \longrightarrow \mathrm{Mg}(\mathrm{OH})_2+'\mathrm{Y}\,'

The products '

\mathrm{X}

' and '

\mathrm{Y}

' respectively are

{H_2}{O_2} \to 2{H^ + } + {O_2} + 2{e^ - };{E^0} = - 0.68V

This equation represents which of the following behaviour of

{\mathrm{H}_\mathrm{2}}{\mathrm{O}_\mathrm{2}}

Which reaction shows oxidizing nature of

{\mathrm{H}_2}{\mathrm{O}_2}

? Which of the following could act as propellent for rockets. (A):

{SiH}_4

AlH_3

and

{NH}_3

are ionic hydrides

(R):Ionic hydrides do not react with water
