Question
Explain the following reaction with the balanced equation.
Ferric oxide is reacted with aluminium.
Solution
Ferric oxide reacts with aluminium to form iron and aluminium oxide. This reaction is known as the thermit reaction.
\[\ce{\underset{\text{Ferric oxide}}{Fe2O_{3(s)}} + \underset{\text{Aluminium}}{2Al_{(s)}} ->[Ignited] \underset{\text{Iron}}{2Fe_{(l)}} + \underset{\text{Aluminium oxide}}{Al2O_{3(s)}}+Heat}\]
