Question

For the redox reaction:

$Zn+N{O}_3^{-}\to Z{n}^{2+}+N{H}_4^{+}$

in a basic medium, coefficients of $Zn,N{O}_3^{-}$ and $O{H}^{-}$ in the balanced equation respectively are:

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

Answer 1

The correct option is C $4,1,10$

$4Zn+1{NO}_3+10H^{+}⟶4Z{n}^{+2}+{NH}_4^{+}+3H_{2}O$

$Zn,{NO}_3^{-}\&{}^{-}OH=4,1,10$
