Question

1. Which of the following metal can not be displaced by carbon?
Iron
Calcium
Lead
Zinc

Answer 1

Explanation:

Carbon is a reducing agent at higher temperatures and from the electrochemical potential point of view or reactivity series carbon is present above many important metals e.g. zinc,iron,copper,silver,gold so it is used to reduce their oxides to extract metals from them but Carbon is present below Potassium so it is not ...

Answer 2

Answer:

Carbon is a reducing agent at higher temperatures and from the electrochemical potential point of view or reactivity series carbon is present above many important metals e.g. zinc,iron,copper,silver,gold so it is used to reduce their oxides to extract metals from them but Carbon is present below Potassium so it is not used as reducing agent for its extraction.
