(a) What is a reactivity series of elements ? How is it developed ? Arrange the following elements as they are arranged in the reactivity series :
Aluminum, Calcium, Copper, Lead
(b) Write balanced chemical equation to show the reaction of iron (III) oxide (Fe2O3) with aluminium.
Solution
(a) A series of metals arranged in the order of their decreasing reactivity/ activity.
By performing displacement reactions
Calcium, Aluminium, Lead, Copper
(b) Fe2O3 + 2Al → Al2O3 + 2Fe + Heat
