2Al + Fe ----> Al2O3 +2Fe
For the reaction above, the mole ratio Aluminium to Aluminuim Oxide is
a.1:1
b.2:1
c.1:2
d.2:2

Answer 1

The mole ratio Aluminium to Aluminum Oxide is 2 : 1

Further explanation

Given

Reaction

2Al + Fe ----> Al2O3 +2Fe

Required

The mol ratio

Solution

If we look at the reaction above, there is an element missing from the reactant i.e oxygen, because the number of atoms and elements involved in the reaction should be the same between the reactants and products.

So the possible and balanced reactions are:

2Al(s) + Fe₂O₃ (s) → Al₂O₃ (s)+ 2Fe (s)

From this reaction the ratio of Al: Al₂O₃ can be determined, which is 2: 1
