Question

Study the following chemical reactions,the most reactive element is
Cu+2Ag(No3)2---->Cu (NO3)2+2Ag
Pb+Cu(No3)2------>PB(No3)2+Cu
Zn+PB(NO3)2----->Zn(No3)2+PB
A. AG (silver)
B. Pb ( lead)
C. Cu(copper)
D.Zn(zinc)

Answer 1

Zn is the answer because zinc is more stronger than given metal..

Mark it as brainliest answer

Answer 2

D). Zn(zinc) is the most reactive element in the given reactions.

Explanation:

• Metals are highly reactive and have a tendency to lose electrons easily and form positive ions, hence metals are called electropositive elements.
• Among the given options, Zinc is the most reactive metal as it comes at the top in the reactivity series while Silver(AG), Lead(Pb), and Cu(copper) rank very low in the series.
• Zin contains a packed D shell and therefore, its inner shell is already filled adequately and despite that, it contains 2 electrons in its outer shell. Thus, it can the elements replace copper, silver, and lead.
