(a)
Interpretation:
Balanced chemical equation for production of lead metal from galena has to be written.
Concept Introduction:
(b)
Interpretation:
The two reactions involved in the production of lead from galena have to be found as redox reactions or not and it has to be explained by identifying the oxidizing and reducing agent.
Concept Introduction:
Oxidizing agent is the one that gets reduced during a chemical reaction and reducing agent is the one that gets oxidized in a chemical reaction. In terms of electron transfer oxidizing agent is the one that donates electrons and reducing agent is the one that accepts electrons. In terms of oxidation number, the oxidizing agent is the one where the element gains electrons results in decrease of oxidation number and reducing agent is the one where the element loses electrons results in increase of oxidation number.
