What element is undergoing reduction (if any) in the following reaction?

Zn(s) + 2 AgNO3(aq) → Zn(NO3)2(aq) + 2 Ag(s)
Zn goes from 0 --> +2
Ag from +3 -->0 reduced
NO3 from -1 --> -2 ?

Respuesta :

The correct answer is Ag. 

Ag is the element that is undergoing reduction in the given reaction. Reduction refers to a gain of electrons and a decrease in oxidation number. So based in all the given reaction, Ag is the element that is undergoing reduction. I hope this answer helped you.
