$\mathrm{X}\underset{{\mathrm{N}}_2}{\overset{∆}{\to }}\mathrm{Y}\stackrel{{\mathrm{H}}_2\mathrm{O}}{⟶}\mathrm{Z}$ (a colourless gas) $\stackrel{{\mathrm{CuSO}}_4}{\to }\mathrm{T}$ (blue colour) :

Then, substances$\mathrm{Y}$ and $\mathrm{T}$ are -

When ${\mathrm{K}}_2\mathrm{O}$ is added to water, the solution becomes basic in nature because it contains a significant concentration of :

If $\mathrm{A}$ is the metalic salt, then the white $\mathrm{ppt}.$ of $\mathrm{D}$ must be of

$\mathrm{NaOH}\left(\mathrm{Solid}\right)+\mathrm{CO}\stackrel{200°\mathrm{C}}{⟶}\mathrm{X} ;$ product $\mathrm{X}$ is :

${\mathrm{CsBr}}_3$ contains :

$\mathrm{EDTA}$ is used in the estimation of :

${\mathrm{KO}}_2$ finds use in oxygen cylinders used for space and submarines. The fact(s) related to such use of ${\mathrm{KO}}_2$ is/are:
