Write balanced equations for :
$(i) \, BF_{3} + LiH \to $
$(ii) \, B_{2}H_{6} + H_{2}O \to $
$(iii) \, NaH + B_{2}H_{6} \to $
$(iv) \, H_{3}BO_{3} \xrightarrow{\Delta }$
$(v) \, Al + NaOH \to $
$(vi) \, B_{2}H_{6} + NH_{3} \to $

(N/A) $(i) \, 2 BF_{3} + 6 LiH \rightarrow B_{2}H_{6} + 6 LiF$
$(ii) \, B_{2}H_{6} + 6 H_{2}O \rightarrow 2 H_{3}BO_{3} + 6 H_{2}$ (Boric acid)
$(iii) \, 2 NaH + B_{2}H_{6} \rightarrow 2 Na[BH_{4}]$ (Sodium borohydride)
$(iv) \, H_{3}BO_{3} \xrightarrow{\Delta } HBO_{2} + H_{2}O$ (Metaboric acid)
$4 HBO_{2} \xrightarrow{\Delta } H_{2}B_{4}O_{7} + H_{2}O$
$H_{2}B_{4}O_{7} \xrightarrow{\Delta } 2 B_{2}O_{3} + H_{2}O$ (Tetraboric acid and Boron trioxide)
$(v) \, 2 Al + 2 NaOH + 6 H_{2}O \rightarrow 2 Na[Al(OH)_{4}] + 3 H_{2}$
$(vi) \, B_{2}H_{6} + 2 NH_{3} \rightarrow 2 BH_{3} \cdot NH_{3}$
