Question

Complete the following reactions and balance them:
(5)
(i)
B + H2SO4 (concentrated) 
(ii)
LiBH4 + H2O 

Answer 1

Complete the following reactions and balance them:

(5)

(i)

$\mathrm{B} + \mathrm{H}_2\mathrm{SO}_4$ (concentrated) $\rightarrow$

(ii)

$\mathrm{LiBH}_4 + \mathrm{H}_2\mathrm{O} \rightarrow$

**Solution.**

1) $2\mathrm{B} + 3\mathrm{H}_{2}\mathrm{SO}_{4} = 2\mathrm{H}_{3}\mathrm{BO}_{3} + 3\mathrm{SO}_{2}$

2) $\mathrm{LiBH}_4 + 4\mathrm{H}_2\mathrm{O} = \mathrm{LiOH} + \mathrm{H}_3\mathrm{BO}_3 + 4\mathrm{H}_2$
