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)) ^(-)`

A

3, 2, 2, 4,1

B

2,3,1,1,5

C

2, 3, 2, 1,5

D

, 2, 1,2, 4

Text Solution

Verified by Experts

The correct Answer is:
D
`x MnO_(4)^(2-) + y H_2O to p MnO_2 + q MnO_(4)^(Theta) + rOH^(Theta)`
Balanced equation is
`3MnO_(4)^(2-) + 2H_2O to MnO_2 + 2MnO_(4)^(-) + 4OH^(-)`
`x = 3, y = 2 , p =1 , q = 2 , r = 4 `
