Question

$Zn\left(s\right)+2AgN{O}_3\left(aq\right)\to Zn\left(N{O}_3{)}_2\right(aq)+2Ag(s)$
Write the chemical equation for oxidation and reduction.

Answer 1

Oxidation:

$Z{n}^o\left(s\right)\to Z{n}^{2+}\left(aq\right)+2e^{-}$

(Oxidation means losing of electrons)

Reduction:

$A{g}^{1+}\left(aq\right)+1e^{-}\to Ag\left(s\right)$

(Reduction means gaining of electrons)
