Question

Write balanced equations for:
(i) $B{F}_3+LiH\to$
(ii) $B_2{H}_6+H_{2}O\to$
(iii) $NaH+B_2{H}_6\to$
(iv) $H_{3}B{O}_3\stackrel{△}{\to }$
(v) $Al+NaOH\to$
(vi) $B_2{H}_6+N{H}_3\to$

Answer 1

The balanced equations are given below:

(i) $2B{F}_3+6LiH\stackrel{450K}{\to }{B}_2{H}_6+6LiF$

(ii) $B_2{H}_6+6H_{2}O\to 2H_{3}B{O}_3\left(orthoboricacid\right)$

(iii) $2NaH+B_2{H}_6\to 2Na\left[B{H}_4\right]\left(sodiumborohydride\right)$

(iv) $H_{3}B{O}_3\stackrel{△}{\to }HB{O}_2\left(metaboricacid\right)+H_{2}O$

$4HB{O}_2\underset{-H_{2}O}{\overset{Heat}{\to }}{H}_2{B}_4{O}_7\stackrel{heat}{\to }2B_2{O}_3\left(borontrioxide\right)+H_{2}O$

(v) $Al+3NaOH\to Al(OH{)}_3+3Na$

$3B_2{H}_6+6N{H}_3\stackrel{heat}{\to }2B_3{N}_3{H}_6+12H_2$
