Answer»

`KMnO_(4) +` conc. `HCl overset( Delta ) ( RARR)`
`KCl + K_(2) Cr_(2) O_()7) + ` conc. `H_(2) SO_(4) overset( Delta ) ( rarr)`
`MnO_(2) = `conc.`HCl overset( Delta ) ( rarr)`
`KCl + F_(2) rarr`

Solution :`4KCl+K_(2)Cr_(2) O_(7) "conc."3H_(2)SO_(4) rarr 2CrO_(2)Cl_(2) + 3K_(2)SO_(4) +3H_(2)O`
