Complete the following chemical equations :
`Z+ 3LiAlH_(4) rarr X + 3LiF + 3AlF_(3) :
X + 6H_(2)O rarr Y + 6H_(2)`

Explanation

To complete the given chemical equations, let's analyze each step systematically.

### Step 1: Identify Z and X in the first reaction
The first equation is:
\[ Z + 3 \text{LiAlH}_4 \rightarrow X + 3 \text{LiF} + 3 \text{AlF}_3 \]

Here, we need to identify what Z is. The presence of LiF and AlF3 suggests that Z is likely a compound containing boron and fluorine, specifically boron trifluoride (BF3). This is because lithium aluminum hydride (LiAlH4) is a reducing agent that can reduce BF3.
