Write balanced equations for:
a.`BF_(3)+LiHto`
b.`B_(2)H_(6)+H_(2)Oto`
c.`NaH+B_(2)H_(6)to`
d.`H_(3)BO_(3)overset(Delta)to`
e.`Al+NaOHto`
f.`B_(2)H_(6)+NH_(3)to`

Explanation

To solve the problem, we need to write balanced chemical equations for the given reactions. Let's go through each reaction step by step.

### a. Reaction of BF₃ with LiH
1. **Write the unbalanced equation**:
\[ \text{BF}_3 + \text{LiH} \rightarrow \text{B}_2\text{H}_6 + \text{LiF} \]
2. **Balance the equation**:
