Describe with one example, how moderately reactive metals (which are in the middle of reactivity series) are extracted.

Academic Chemistry NCERT Class 10

Moderately reactive metals are extracted by the reduction of their oxides with carbon, aluminum sodium, or calcium.

Example:

Roasting: When zinc sulphate is strongly heated in the air, it forms zinc oxide and sulphur dioxide.

Reduction: Zinc oxide is heated with carbon to form zinc metal.

Explain giving one example, how highly reactive metals (which are high up in the reactivity series) are extracted.
How are the less reactive metals (which are quite low in the reactivity series) extracted? Explain with the help of an example.
List the five metals in order of reactivity, starting with the most reactive.
Carbon cannot reduce the oxides of sodium, magnesium and aluminium to their respective metals. Why? Where are these metals placed in the reactivity series? How are these metals obtained from their ores? Take an example to explain the process of extraction along with chemical equations.
(a) What is meant by the reactivity series of metals? Arrange the following metals in an increasing order of their reactivities towards water:Zinc, Iron, Magnesium, Sodium (b) Hydrogen is not a metal but still it has been assigned a place in the reactivity series of metals.
