निम्न में से कौन-सी समीकरण सन्तुलित है?

Options

A. `5BiO_(3)^(-)+22H^(-)+Mn^(2+) to 5Bi^(3+)+7H_(2)O+MnO_(4)^(-)`
B. `5BiO_(3)^(-)+14H^(+) +2Mn^(2+) to 5Bi^(3+)+7H_(2)O+2MnO_(4)^(-)`
C. `2BiO_(3)^(-)+4H^(+)+Mn^(2+) to 2Bi^(3+)+2H_(2)O+MnO_(4^(-)`
D. `6BiO_(3)^(-) +12H^+ +3Mn^(2+) to 6Bi^(3+)+6H_(2)O+3MnO_(4)^(-)`

Answer

B

Explanation

`underset("आवेश ")(5BiO_(3)^(-))+14H^(+) +underset(-5+14+4=13)(2Mn^(2+)) to underset(5 xx 3+0+(2 xx 1))(5Bi^(3+))+7H_(2)O+2MnO_(4)^(0)`
