Answer 2

Answer:

16.

a) CuSO4 + Fe gives FeSO4 + Cu ( iron displaces copper atom from copper sulfate to form iron sulfate or ferrous sulfate)

b) FeSO4 + Zn ( iron displaces zinc atom from zinc sulfate to form iron sulfate)

c) FeSO4 + Mg ( iron displaces magnesium atom from magnesium sulfate to form iron sulfate)

d) Fe2(SO4) + ca ( iron displaces calcium atom from calcium sulfate to form iron sulfate)
