question_answer 1)

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)\[{{H}_{3}}B{{O}_{3}}\xrightarrow{Heat}\] (v) \[Al+NaOH+{{H}_{2}}O\to \] (vi)\[{{B}_{2}}{{H}_{6}}+N{{H}_{3}}\to \]  

Answer:

(i) \[2B{{F}_{3}}+6LiH\to {{B}_{2}}{{H}_{6}}+6LiF;\] (ii) \[{{B}_{2}}{{H}_{6}}+6LiH\to 2{{H}_{3}}B{{O}_{3}}+6{{H}_{2}};\] (iii) \[2NaH+{{B}_{2}}{{H}_{6}}\to 2NaN{{H}_{4}};\] (v) \[2Al+2NaOH+6{{H}_{2}}O\to 2Na[Al{{(OH)}_{4}}]+3{{H}_{2}};\] (vi)\[{{B}_{2}}{{H}_{6}}+2N{{H}_{3}}\to {{B}_{2}}{{H}_{6}}\cdot 2N{{H}_{3}}\]
