Question

The following redox reaction occurs in basic medium `NO_(3)^(-)Zn(s)toZn^(2+)+NH_(4)^(+)` when the above reaction is balanced such that the stoichiometric coefficients are in smallest whole number ratio, then the difference of stoichiometric coefficient of Zn (s) and `OH^(-)` ion will be:
A. 4,1,7
B. 7,4,1
C. 4,1,10
D. 1,4,10

Answer 1

Correct Answer - C
`4Zn+NO_(3)^(-)+7H_(2)Orarr4Zn^(2+)+NH_(4)^(+)+10OH^(-)`
