aK (2) Cr (2) O (7) + b KCl + c H (2) SO...

`aK _(2) Cr _(2) O _(7) + b KCl + c H _(2) SO _(4) to x Cr O _(2) Cl _(2) + y KHSO _(4) + zH_(2)O.` The above equation balances when :

A

`a=2, b=4, c=6, and x=2, y=6, z=3`

B

`a=2, b=4, c=6, and x=6, y=2, z=3`

C

`a=6, b=4, c=2, and x=6, y=3, z=2`

D

`a=1, b=4, c=6, and x=2, y=6, z=3`

Text Solution

Verified by Experts

The correct Answer is:
D
`a K _(2) underset(1) ( Cr _(2)) O _(7) + underset( 4) ( b K Cl)+ underset( 6) ( c H _(2) SO _(4))to underset( 2 ) ( x Cr O _(2)) Cl _(2) + underset( 6) (y KHOSO _(4)) + underset(3) ( z H _(2)O)`
