Question

How many of the following reactions are correct?

1. $X e F_{6} + N a F \to N a^{+} [X e F_{7}]^{-}$

2. $X e F_{4} + S b F_{5} \to [X e F_{3}]^{+} [S b F_{6}]^{-}$

3. $6 X e F_{4} + 12 H_{2} O \to 4 X e + 2 X e O_{3} + 24 H F + 3 O_{2}$

4. $X e F_{6} + 2 H_{2} O \to X e O_{2} F_{2} + 4 H F$

5. $X e F_{6} + H_{2} O \to X e O F_{4} + 2 H F$

6. $N O_{3}^{-} + 4 Z n + 7 O H^{-} + 6 H_{2} O \to N H_{3} + 4 [Z n (O H)_{4}]^{2 -}$
