What will be observed when a piece of Ag metal is added to a Pb(NO3)2 solution? What will be observed when a piece of Ca metal is added to a AgNO3 solution?

Part a)

No Reaction

Part b)

CaNO3 is formed

Explanation:

Part a)

Silver is less reactive than lead and hence when Ag metal is added to a Pb(NO3)2 solution there will be no reaction

Ag (s) + Pb(NO3)2 (aq) --> Ag (s) + Pb(NO3)2 (aq)

Part b)

Calcium is more reactive than silver and hence when calcium is added to the solution of AgNO3, it will replace Ag from the AgNO3 and itself form compound with NO3 2- ion.

The reaction for the same is

Ca (s) + AgNO3 = CaNO3 + Ag (s)

because u need two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei to form isotopes.

so since they all have the same shape? i mean maybe because m& m and reeses are both chocolates
