Question

State, giving chemical equations, what happens when
(a). Iron reacts with copper sulphate solution.
(b).Silver reacts with copper sulphate solution.
(c). Magnesium reacts with dilute sulphuric acid.
(d). Sodium is put into water.

Answer 1

CuSO4 + Fe = FeSO4 + Cu

Iron displaced Copper . So the reaction between copper sulphate and iron is a displacement reaction.

Answer 2

A) Fe + CuSO4 ----> FeSO4 + Cu

Iron+ Copper -----> Iron + Copper

sulfate sulfate

sulfate sulfate B) Ag + CuSO4 -----> No reaction

sulfate sulfate B) Ag + CuSO4 -----> No reaction Silver + Copper

sulfate sulfate B) Ag + CuSO4 -----> No reaction Silver + Copper sulfate

sulfate sulfate B) Ag + CuSO4 -----> No reaction Silver + Copper sulfate C) Mg + H2SO4 ------> MgSO4 + H2

sulfate sulfate B) Ag + CuSO4 -----> No reaction Silver + Copper sulfate C) Mg + H2SO4 ------> MgSO4 + H2 Magnesium +

sulfate sulfate B) Ag + CuSO4 -----> No reaction Silver + Copper sulfate C) Mg + H2SO4 ------> MgSO4 + H2 Magnesium + Hydrochloric acid----> Magnessium+ Hydrogen

sulfate

D) 2Na + 2H2O -----> 2NaOH + H2

Sodium+ Water ----> Sodium + Hydrogen

hydroxide

Here you go

hope it helps
