For the redox reaction, `Zn + NO_3^(-) to Zn^(2+) + NH_4^(+)` in basic medium, the coefficients of `Zn, NO_3^(-)` and `OH^(-)` in the balanced equation are respectively

Options

A. 4,1,7
B. 7,4,1
C. 4,1,10
D. 1,4,10

Answer

C

Explanation

`Zn to Zn^(+2) + 2e^(-)`
`( NO_(3)^(-) +H_2 O + 8e^(-) to NH_(4)^(-) + 10 OH^(-))/(4Zn +NO_(3)^(-) + 7 H_2 O to 4 Zn^(+2) + NH_(4)^(+) + 10 OH^(-))`
