Oxides of moderately reactive metals like Zinc, Iron, Nickel, Tin and Copper etc. are reduced by using
Explain with suitable example the metal used to reduce the oxides of less reactive, moderately reactive, highly reactive metals.
Metals like iron, copper, aluminium and zinc are given to a student. The correct decreasing order of reactivity of these metals written by the student is:
CuSO4+Fe →FeSO4+ Cu
FeSO4+Zn →ZnSO4+ Fe
Which of the following statement is true on the basis of above reactions?
