Question

Extraction of Metals of *Low reactive series*
a. name of the metal
b.reaction involved​

Answer 1

Answer:

Explanation:

Learn how the reactivity series helps us to predict how metals will react with BBC ... be shared with companies involved in the delivery and/or personalisation of ads ... A more reactive metal will displace a less reactive metal from a compound. ... into the reactivity series because these elements can be used to extract metals.

Answer 2

Explanation:

Metals of low reactivity series are generally extracted by the process of roasting and calcination. Roasting is the extraction of metals by heating in presence of oxygen i.e. that Cinnebar is heated with o2 which gives SO2 and Hg.

HgS + O2---------- Hg + SO2

While calcination is the heating the ore without oxygen i.e. Ferric Oxide(Fe3O4) is with carbon then they release Fe and CO2
