Give the correct order of initials T or F for following statements. Use T if statements is true and F if if false.
`(I)` Number of `S-S` bond in `H_(2)S_(n)O_(6)` are `(n+1)`
`(II)` When `F_(2)` reacts with water gives `HF,O_(2)` and `O_(3)`
`(III)` `LiNO_(3)` and `BaCl_(2)` compounds are used in the fire works
`(IV)` Be and Mg hydrides are ionic and polymeric

Explanation

Let's analyze each statement one by one to determine whether they are true (T) or false (F).

### Statement Analysis:

**(I)** Number of `S-S` bonds in `H₂SₙO₆` are `(n+1)`.
- In the compound `H₂SₙO₆`, the sulfur atoms are connected to each other. The number of `S-S` bonds is actually `n-1` because each sulfur atom (except the terminal ones) forms a bond with the next sulfur atom in the chain. Therefore, this statement is **False (F)**.

**(II)** When `F₂` reacts with water, it gives `HF`, `O₂`, and `O₃`.
- When fluorine reacts with water, it primarily produces hydrogen fluoride (HF) and oxygen (O₂) but does not produce ozone (O₃). The reaction can be summarized as:
\[ 2F₂ + 2H₂O \rightarrow 4HF + O₂ \]
Therefore, this statement is also **False (F)**.

**(III)** `LiNO₃` and `BaCl₂` compounds are used in fireworks.
- Lithium nitrate (`LiNO₃`) is indeed used in red fireworks, and barium chloride (`BaCl₂`) is used in green fireworks. Therefore, this statement is **True (T)**.

**(IV)** Be and Mg hydrides are ionic and polymeric.
- Beryllium (Be) and magnesium (Mg) hydrides are not ionic; they are covalent due to the relatively high electronegativity of Be and Mg. While they can form polymeric structures, they are not classified as ionic. Therefore, this statement is **False (F)**.

### Final Order of Statements:
1. (I) F
2. (II) F
3. (III) T
4. (IV) F

### Summary of Answers:
- (I) F
- (II) F
- (III) T
- (IV) F
