Answer to Question #120265 in Chemistry for Befikir

Question

The equation for the ”thermite” reaction between aluminum and
iron(III)oxide is
2Al(s) + Fe2O3(s) → 2Fe(l) + Al2O3(s)
What mass of aluminum powder would be needed to react completely
with 16g of dried iron (III) oxide?

Answer 1

Solution:

The balanced chemical equation:

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

Calculate the grams of aluminum powder used if 16 g of dried iron (III) oxide reacts completely.

Answer: 5.4 g of aluminum powder (Al) would be needed.
