In the unbalanced reaction: `Al + KMnO_4 +H_2SO_4 to K_2SO_4 + Al_2 (SO_4)_3 + MnSO_4+H_2O`
If the stoichiometric coefficients of `Al, H_2SO_4MnSO_4` and `H_2O` are w,x,yand z respectively, the numerical value are

A

`2.0`

B

`1.6`

C

`1.2`

D

`2.4`

Text Solution

Verified by Experts

The correct Answer is:
B
`10 Al + 6 KmNO_4 + 24 H_2 SO_4 to 3 K_2 SO_4 + 5Al_2 (SO_4)_3 + 6MnSO_4 + 24 H_2 O`
` (x)/(y) =( 24 )/(6 )=4 , (z)/(w)=(24)/(10) = 2.4 , 4-2.4 = 1.6`
