Question

Lead is listed below zinc in the activity series.

Answer 1

Answer:

Zn+Pb(NO3)2→Zn(NO3)2+Pb

Answer 2

Answer: The chemical equation is written below.

Explanation:

Single displacement reaction is defined as the reaction in which more reactive element displaces a less reactive element from its chemical reaction.

The reactivity of metal is determined by a series known as reactivity series. The metals lying above in the series are more reactive than the metals which lie below in the series.

$A+BC\rightarrow AC+B$

When lead nitrate is reacted with zinc metal, it leads to the formation of zinc nitrate and solid lead.

The chemical equation for the above reaction follows:

$Pb(NO_3)_2(aq.)+Zn(s)\rightarrow Zn(NO_3)_2(aq.)+Pb(s)$

As, zinc lies above in the reactivity series than lead, so it will easily displace lead from its chemical reaction.

Hence, the chemical equation is written above.
