Answer» tion:\BOLD{\mathrm{Fe}+\mathrm{CuSO}_{4} ARROW \mathrm{FESO}_{4}+\mathrm{Cu}}Fe+CuSO 4 arrowFeSO 4 +Cu is a single replacement or displacement reaction.It is because, in this reaction, the highly reactive metal iron replaces the Copper in copper SULPHATE by giving up two electrons and gets oxidized and FORMS a new compound called ferrous sulphate. The copper present in the compound gets reduced by gaining two electrons and is released from it.As a highly reactive metal (iron) replaces a low reactive metal (copper) in the given reaction it is inferred that \bold{\mathrm{Fe}+\mathrm{CuSO}_{4} arrow \mathrm{FeSO}_{4}+\mathrm{Cu}}Fe+CuSO 4 arrowFeSO 4 +Cu a single replacement or displacement reaction.please select me the brainliest and follow me |
