Write balanced equations for:
(i) `BF_(3) + LiH rarr`
(ii) `B_(2)H_(6) + H_(2)O rarr`
(iii) `NaH + B_(2)H_(6) rarr`
(iv) `H_(3)BO_(3)overset(Delta)rarr`
(v) `Al + NaOH rarr`
(vi) `B_(2)H_(6) + NH_(3) rarr`

Explanation

a.`2BF_(3)+6liHtounderset("Diborane")(B_(2)H_(6))`
b. `underset("Diborane")(B_(2)H_(6)+)6H_(2)Otounderset("acid")underset("Orthoboric")(2B(OH)_(3))+6H_(2)`
c.`2NaH+B_(2)H_(6)to2Na^(o+)[BH_(4)]^(ө)`
d. `underset("Boric acid")(H_(3)BO_(3))overset(Delta)tounderset("acid")underset("Metaboric")(HBO_(2))+H_(2)O`
`4HBO_(2)overset(Delta)tounderset("Tetraboric acid")(H_(2)B_(4)O_(7))+H_(2)O`
`H_(2)B_(4)O_(7)overset(Delta)tounderset("trioxide")underset("Borton")(2B_(2)O_(3))+H_(2)O`
e.`2Al+2NaOH+6H_(2)Otounderset("aluminate(III)")underset("Sodium tetrahydroxo")(2Na^(o+)[Al(OH)_(4)])^()+3H_(2)uarr`
