Answer 1

Answer:because silver(ag) is less reactive than copper(cu)

Explanation:

Since reaction depends upon the reactivity of metals and non metals. Hence, copper reacts more than silver and forms a silvery layer on the coin.

Reaction: Cu(s) + 2AgNO3 --> Cu(NO3)2(aq) + 2Ag(s)

Answer 2

Answer:

beacause silver(ag) less reactive than copper
