The set of numerical coefficients that balances the following equation is
`K_2 CrO_4+ HCl rarr K_4 Cr_2O_7 + KCl +H_2O`.

A

` 2,2,1,1,1,`

B

` 2,1,1,2,1`

C

` 1,1,2,2,1`

D

` 2,2,1,2,1`

Text Solution

Verified by Experts

The correct Answer is:
D
To balance Cr on both sides, multiply ` K_2CrO_4` by `2`: to balance K on both sides, multiply ` KCl` by 2: and to balance `Cl` on both sides, multiply ` HCl` by 2:
`2K_2CrO_4 + 2HCl rarr K_2Cr_2O_7 + 2KCl+H_2O`.
