Question

considering ellingham diagram which of the following metals can be used to reduce Alumina ferrous zinc copper magnesium

Answer 1

An Eallingham diagram is a graph showing the temperature dependence of the stability for compounds.

This analysis is usually used to evaluate the ease of reduction of metal oxides.

The lower the position of a metal's line in the Ellingham diagram the greater the stability of the oxide.

Aluminum's curve lies below most metals thus can act as reducing agent.

A given metal oxide can reduce the oxides of other metals whose lines lie above its line on the diagram.

Since Magnesium oxide's line lies below Aluminum, Magnesium can tgus reduce Alumina.

The answer is thus :

Magnesium.

Answer 2

Answer:Mg

Explanation:

That's bcoz the metal which is more reactive than Al will reduce alumina. Beacoz it will have more negative value if ∆G and thus magnesium
