Question

A student writes the chemical equation of the reaction between lead and copper chloride. Pb(s) + CuCl₂(aq) →PbCl₂(aq) + Cu(s) Which option explains the reason for the formation of lead chloride?
copper is more reactive than lead
lead is less reactive than copper
lead and copper are equally reactive
lead is more reactive than copper

Answer 1

Answer:

(i)Here displacement reaction occurs because lead powder reacts with chlorine gas removing solid copper from copper.

(ii)Chloride and produce lead chloride.The copper atom inn copper chloride is displaced by the lead atom and this results in the formation of lead chloride and copper.Hence this of reaction is known as displacement reaction.

Answer 2

Answer:

(d) lead is more reactive than copper.
