The coefficients X,y,p,q and r in the following balanced equations respectively are :
`xMnO_(4(aq)) ^(2-) + yH_(2) O _((l)) to pMnO _(2(s)) + q MnO _(4( aq)) ^(-) + rOH_((aq)) ^(-)`

Options

A. `3,2,2,4,1`
B. `2,3,1,1,5`
C. `2,3,2,1,5`
D. `3,2,1,2,4`

Answer

D

Explanation

Given,
`xMnO _(4(aq)) ^(2-) + yH O _((l)) to pMnO_(2(s)) + qMnO _(4(aq)) ^(-)+r OH_((aq)) ^(-)`
The balanced equation to obtyain the coefficients x,y,p,q and r is given by,
`3MNO _(4(aq)) ^(2-) + 2H _(2) O (L) to MNO_(2(s)) + 2MNO _(4(aq)) ^(-) + 4OH _((aq)) ^(-) `
`therefore x =3, y=2, p=1, q=2, r=4`
