Question

write the equation when aluminium reacts with ironoxid​

Answer 1

$Answer:-$

The equation for this reaction is: 2 Al(s) + Fe 2O 3(s) --> 2Fe (s) + Al 2O 3 (s). The large decrease in the energy of the system is a consequence of the high charge concentration on the aluminum ion due to its small size.

Answer 2

Answer:

This is a displacement reaction as aluminium displaces iron in iron(III)oxide to form aluminium oxide. Also it is a redox reaction as both oxidation of aluminium and reduction of iron is taking place. The equation can be written as: 2Al(s)+Fe2O3(s)→Al2O3(s)+2Fe(l)+heat
