Question

Consider the following reaction :
`xMnO_(4)^(-)+yC_(2)O_(4)^(2-)+zH^(+) to xMn^(2+)+2yCO_(2)+(z)/(2)H_(2)O`
The value of x, y and z in the reaction are, respectively.
A. 2,5 and 16
B. 5,2 and 8
C. 5,2 and 16
D. 2,5 and 8

Answer 1

Correct Answer - A
The balanced chemical equation is:
`2MnO_(4)^(-)+5CrO_(4)^(2-)+16H^(+) to 2Mn^(2+)+10CO_(2)+8H_(2)O`
`therefore` x=2, y=5, z=16]
