The molar ratios are:
Fe₂O₃ : Al = 1 : 2
Al : Fe = 2 : 2 (or) 1 : 1
Al : Al₂O₃ = 2: 1
Step-by-step explanation:
To find the correct mole ratio, we have to write the balanced reaction. Aluminium and iron oxide reacts with each other to form Aluminium oxide and iron and releases a lot amount of energy in the form of heat and light and it is highly exothermic reaction.
2 Al + Fe₂O₃ → Al₂O₃ + 2 Fe
Mole ratios are:
Fe₂O₃ : Al = 1 : 2
Al : Fe = 2 : 2 (or) 1 : 1
Al : Al₂O₃ = 2: 1
So Using the Balanced equation, the molar ratios of the required substances were found.
