When orthoboric acid $({H_3}B{O_3})$ is heated, the residue left is
Metaboric acid
Boron
Boric anhydride
Borax
(c) $2{H_3}B{O_3} \to {B_2}{O_3} + 3{H_2}O$.
Boron fluoride exists as $BF_3$ but boron hydride doesn't exist as $BH_3$ . Give reason. In which form, does it exist ? Explain its structure.
Which one is used as a bye-product in Serpeck's process
The incorrect statement regarding above reactions is
$\mathop {Al}\limits_{Metal} \xrightarrow{{HCl(aq.)}}'X' + Gas\,'P'$
$\mathop {Al}\limits_{metal} \xrightarrow[{ + {H_2}O}]{{NaOH\,(aq.)}}'Y' + Gas\,'Q'$
Which of the following statements about ${H_3}B{O_3}$ is not correct
A nonmetallic element of group $-13$, used in making bullet proof vests is extremely hard solid of black colour. It can exist in many allotropic forms and has unusually high melting point. Its trifluoride acts as Lewis acid towards ammonia. The element exhibits maximum covalence of four. Identify the element and write the reaction of its trifluoride with ammonia. Explain why does the trifluoride acts as a Lewis acid.
