Borax is converted into crystalline boron by the following steps
${B{orax}}\xrightarrow{X}{H_3}B{O_3}\xrightarrow{\Delta }{B_2}{O_3}\xrightarrow[\Delta ]{Y}B$,
$X$ and $Y$ are respectively
A
$HCl, Mg$
B
$HCl, C$
C
$C, Al$
D
$HCl, Al$
Solution
${B_2}{O_3}\xrightarrow[\Delta ]{{Al}}B\left( {crystalline} \right)$, ${B_2}{O_3}\xrightarrow[\Delta ]{{Mg}}B\left( {Amorphous} \right)$
