Answer

Let's complete the reactions step by step:

### (i) Reaction of `XeF2 + H2`
**Reaction:**
\[ \text{XeF}_2 + \text{H}_2 \rightarrow \text{Xe} + 2 \text{HF} \]

### (ii) Reaction of `XeF6 + SiO2`
**Reaction:**
1. First, `XeF6` reacts with `SiO2` to form `XeOF4` and `SiF4`.
\[ \text{XeF}_6 + \text{SiO}_2 \rightarrow \text{XeOF}_4 + \text{SiF}_4 \]

2. Then, `XeOF4` reacts with `SiO2` to form `XeO2F2` and `SiF4`.
\[ \text{XeOF}_4 + \text{SiO}_2 \rightarrow \text{XeO}_2\text{F}_2 + \text{SiF}_4 \]

3. Finally, `XeO2F2` reacts with `SiO2` to produce `2XeO3` and `SiF4`.
\[ \text{XeO}_2\text{F}_2 + \text{SiO}_2 \rightarrow 2 \text{XeO}_3 + \text{SiF}_4 \]

### (iii) Reaction of `XeF6 + NH3`
**Reaction:**
\[ \text{XeF}_6 + 8 \text{NH}_3 \rightarrow \text{Xe} + 6 \text{NH}_4\text{F} + \text{N}_2 \]

### (iv) Reaction of `XeF6 + H2O`
**Reaction:**
\[ \text{XeF}_6 + 3 \text{H}_2\text{O} \rightarrow \text{XeO}_3 + 6 \text{HF} \]

### (v) Reaction of `XeF6 + SbF5`
**Reaction:**
\[ \text{XeF}_6 + \text{SbF}_5 \rightarrow \text{XeF}_5^+ + \text{SbF}_6^- \]

### (vi) Reaction of `XeF4 + 4KI`
**Reaction:**
\[ \text{XeF}_4 + 4 \text{KI} \rightarrow \text{Xe} + 4 \text{KF} + 2 \text{I}_2 \]

### (vii) Reaction of `XeF4 + BCl3`
**Reaction:**
\[ \text{XeF}_4 + 4 \text{BCl}_3 \rightarrow 3 \text{Xe} + 4 \text{BF}_3 + 6 \text{Cl}_2 \]
